Cautions to be Used during Operation

●

WARNING

Do not touch the insides of the scanner, transmitterreceiver and display unit.

Touching any high voltage area, you will get an electric shock. For maintenance, inspection and adjustment of internal parts of these equipment, consult with our sales office or distributor in your district.

Since the scanner radiator rotates, do not approach it.

The scanner may start rotating suddenly, and consequently any person may be struck and be injured. We recommend you to install the scanner radiator on the roof of the wheel house, flying bridge, trestle, radar mast or any other high position so that no person can approach it. When servicing the scanner, set the scanner safety switch to the “OFF” position.

SCANNER RADIATION HAZARD

Never look up the antenna from which radiation is being output from a distance less than the following.

Injury may result from exposure to radiation produced by the antenna (particularly effects to the eyes) at a distance from the central front face of the antenna less than:

0.6 meter for NKE-1059/1052 (Radiation power density of 10 W/m 2 )

1.1 meter for NKE-1079/1075 (Radiation power density of 10 W/m 2 )

25 cm for NKE-1079/1075 (Radiation power density of 100 W/m 2 )

Install the scanner at any place higher than any person.

If being exposed directly to electric wave at close range, you may suffer adverse influence.

When approaching the scanner for maintenance or inspection, set the power switch of the display unit to the

“OFF” or “STBY” position.

If being exposed directly to electric wave to close range, you may suffer adverse influence.

– iii –

CAUTION

Use these radar only as assisting devices for navigation.

Also, the officer should make the final decision for maneuvering by himself.

Use ARPA only as assisting device for navigation. Also, the officer should make the final decision for maneuvering by himself.

ARPA’s information such as vector, target value data, alarm, etc. may contain some errors. Also, targets which cannot be detected with these radar cannot be tracked at their acquisition points.

◆◆◆◆ PRECAUTIONS BEFORE OPERATION ◆◆◆◆

■

Cautions for high voltage

High voltages from hundreds volts to tens of thousands volts are to be applied to the electronic equipment such radio and radar devices. You do not face any danger during normal operation, but sufficient cares are required for maintenance, inspection and adjustment of their internal components. (Maintenance, check-up and adjustment of the inside of the equipment are prohibited except by maintenance specialists.)

High voltages of tens of thousands volts are so dangerous as to bring an instantaneous death from electric shock, but even voltages of hundred volts may sometimes lead to a death from electric shock. To prevent such an accident, make it a rule to turn off the power switch, discharge capacitors with a wire surely earthed on an end and make sure that internal parts are no longer charged before you touch any parts inside these devices. At the time, wearing dry cotton gloves ensures you further to prevent such danger. It is also a necessary caution to put one of your hands in the pocket and not to use your both hands at the same time.

It is also important to select a stable foothold always to prevent additional injuries once you were shocked by electricity. If you were injured from electric shock, disinfect the burn sufficiently and get it taken care of promptly.

■

What to do in case of electric shock

When finding a victim of electric shock, turn off the power source and earth the circuit immediately.

If it is impossible to turn off the circuit, move the victim away promptly using insulators such as dry wood plate and cloth without touching the victim directly.

In case of electric shock, breathing may stop suddenly if current flows to the respiration center in the brain. If the shock is not so strong, artificial respiration may recover breathing. When shocked by electricity, the victim will come to look very bad with weak pulse or without beating, resulting in unconsciousness and rigidity.

– v –

◆◆◆◆◆◆◆◆◆ FIRST-AID TREATMENTS ◆◆◆◆◆◆◆◆◆

First-aid treatments

As far as the victim of electric shock is not in dangerous condition, do not move him and practice artificial respiration on him immediately. Once started, it should be continued rhythmically.

(1) Do not touch the victim confusedly as a result of the accident, but the rescuer may also get an electric shock.

(2) Turn off the power source calmly and move the victim away quietly from the electric line.

(3) Call a physician or ambulance immediately or ask someone to call a doctor.

(4) Lay the victim on his back and loosen his necktie, clothes, belt, etc.

(5) a. Examine the victim’s pulse.

b. Examine his heartbeat bringing your ear close to his heart.

c. Examine his breathing bringing the back of your hand or your face close to his face.

d. Check the size of the pupils of his eyes.

(6) Open the victim’s mouth and take out artificial teeth, cigarette or chewing gum if any. Keep his mouth open, stretch his tongue and insert a towel or the like in his mouth to prevent the tongue from suffocating. (If it is hard to open his mouth due to set teeth, open it with a screwdriver and insert a towel in this mouth.)

(7) Then, close his mouth so that foaming mucus does not accumulate inside.

– vi –

When pulse is beating but breathing has stopped

(Mouth-to-mouth respiration) Fig.1

(1) Tilt the victim’s head back as far as this face looks back. (A pillow may be inserted his neck.)

(2) Push his jaw upward to open his throat wide (to spread his airway).

(3) Pinch the victim’s nostrils and take a deep breath, block his mouth completely with yours and blow into his mouth strongly. Take a deep breath again and blow into his mouth. Continue this 10 to 15 times a minute (blocking his nostrils).

(4) Carefully watch that he has recovered his natural breathing and stop practicing artificial respiration.

(5) If it is difficult to open the victim’s mouth, insert a rubber or vinyl tube into one of his nostrils and blow into it blocking the other nostril and his mouth completely.

(6) When the victim recovers consciousness, he may try to stand up suddenly, but let him lie calmly and serve him with a cup of hot coffee or tea and keep him warm and quiet. (Never give him alcoholic drinks.)

Method of mouth-to-mouth respiration by raising head

(1) Raise the victim’s head. Support his forehead with one of your hand and his neck with the other hand. / q

When you tilt his head backward, the victim, in most cases, opens his mouth to the air. This makes mouth-to-mouth respiration easy.

(2) Cover his mouth as widely as possible with yours and press your cheek against his nose / w or, pinch his nostrils with your fingers to prevent air from leaking. / e

(3) Blow into his lungs. Continue blowing into his mouth until his breast swells. Blow into his mouth as quickly as possible for the first 10 times.

Fig.1 Mouth-to-mouth respiration

– vii –

When both pulse and breathing have stopped

Perform the (Cardiac massage) Fig.2 and (Mouth-to-mouth respiration) Fig.1

When no pulse has come not to be felt, his pupils are open and no heartbeat is heard, cardiac arrest is supposed to have occurred and artificial respiration must be performed.

(1) Place your both hands, one hand on the other, on the lower one third area of his breastbone and compress his breast with your elbows applying your weight on his breast so that it is dented about 2 cm (Repeat compressing his breast 50 times or so a minute). (Cardiac massage)

(2) In case of one rescuer,

Repeat cardiac massages about 15 times and blow into his mouth 2 times quickly, and repeat this combination.

In case of two rescuers,

One person repeats cardiac massages 5 times while the other person blow into his mouth once, and they shall repeat this combination. (Perform the cardiac massage and mouth-tomouth respiration)

(3) Examine his pupils and his pulse sometimes. When the both have returned to normal, stop the artificial respiration, serve him with a cup of hot coffee or tea and keep him warm and calm while watching him carefully. Commit the victim to a medical specialist depending on his condition. (Never give him alcoholic drinks.) To let him recover from the mental shock, it is necessary for persons concerned to understand his situations and the necessary treatments.

In addition, the equipment has the functions of color display setting (4 views), own track display, NAV line and marker displays, TM (True Motion) presentation, Self-diagnostic facilities, and radar performance monitoring (Performance Monitor). As an option, the radar of 3-units switchover function

(Interswitch) is also available.

1.1.2 ARPA Functions

The ARPA functions that the JMA-9800 series incorporates will be outlined below.

[ !

] First Stage: Target Detection from Radar Information

This work corresponds to plotting targets by hand on the radar display. Assume that a ship is approaching the own ship. You can catch the ship on the radar. Signals from the ship are processed with the data processor and are transferred to the computer as signals of bearing and range related to the own ship. In this stage, the system has the functions to quantize radar information, to reject noises, to eliminate any information other than ship information and to transfer necessary position data of ships to the computer.

[ @ ] Second Stage: Target Tracking

Targets are plotted at intervals of 3 to 6 minutes with the radar, but tracking on this system is to plot them electrically at intervals of fixed times. This means to compare target position data to be detected every moment with those detected previously so as to check if they are of the same target and also to save data of the target in its file so as to calculate changes of position data of the target.

[ # ] Third Stage: Judgment of Existence of Ship in Danger of Collision

In this stage, the system calculates speeds and courses of a target ship from ever-changing position data of the target ship obtained in the previous stage so as to judge existence of any danger of collision.

After the calculation, the system can easily calculate the Closest Point of Approach (CPA) to the own ship and the time required to reach the CPA (TCPA = Time to CPA). Both the CPA and the TCPA are compared with the preset values previously set according to the situations of the own ship so as to judge existence of any danger of collision.

1.1 FUNCTIONS

.

[ $ ] Fourth Stage: Indication

The above information must be informed to the officer maneuvering the own ship. A variety of indicating methods are available including CRT display and numerical indicator, and various data are available.

This system indicates unprocessed video, vectors (to be selected from true vector and relative vector) of other ships and identification marks of danger ship or safe ship for these ships on the usual radar scope.

When the target ship is a danger one, the system will sound an alarm and turns on the alarm lamp to alert the officer.

COLLISION AVOIDANCE

……Problems of Collision Avoidance in Navigation …………………

Marine collision avoidance is one of the problems that have been recognized from of old. Now, it will be described briefly who the collision avoidance is positioned among the navigational aid problems.

The navigation pattern of all mobile craft constitues a system with some closed loops regardless of the media through which the mobile craft travels, whether air, water, the boundary between air and water, or space. This pattern consists of two closed loops in principle, one of which is a collision with another mobile craft and the other is a loop of finding a right and safe way to reach a predeterminate destination.

Fig.1.19 shows the conceptual diagram of navigation pattern by MR. E.W. Anderson. The closed loop of collision avoidance is shown on the left side and the closed loop of finding a right course on the right side.

……Marine Accidents and Collisions …………………………………

Among marine accidents, collision accidents have been highlighted as the tonnages and speeds of ships become higher along with the increase in traffic at sea. If a tanker carrying dangerous articles such as crude oil collides with any other vessel, then not only the vessels involved with the accident but other vessels in the vicinity, port facilities, inhabitants in the coastal area as well as marine resources may also suffer immeasurable damages and troubles. Collision accidents have a high percentage of the marine accidents that have occurred in recent years. To cope with these problems, any effective measures are needed and some equipment to achieve collision avoidance requirements have been developed at rapid strides.

1.6 COLLISION AVOIDANCE

.

……Basic Concept of Collision Avoidance ……………………………

There are two aspects in collision avoidance: collision prediction and avoidance. Collision prediction is to predict that two or more vessels will happen to occupy the same point at the same time, while collision avoidance is to maneuver vessels not to occupy the same point at the same time.

In practical operation of vessels, a spot of collision has to be deemed to be a single point but a closed zone. This closed zone is conceptually defined as a CPA (Closest Point of Approach). In collision prediction, the time to be taken until a ship reaches the CPA is defined as a TCPA (Time to CPA).

Fig.1.20 shows a diagram called “Collision Triangle”.

……Relative Vector and True Vector ……………………………………

From two points of view, collision prediction and avoidance, it is necessary to obtain the relative vector of other ship for prediction and the true vector of other ship for collision avoidance in order to grasp other ship’s aspect. The relationship between the relative vector and true vector is shown in Fig.1.21.

Both rough CPA and TCPA can be obtained easily from the relative speed vector of other ship. This method has an advantage that the risks of collision with all other ships within the radar range can be seen at a glance. On the other hand, the course and speed of other ship can easily be obtained from its true speed vector, enabling other ship’s aspect to be seen at a glance. Thus, the aspects of other ships

(transverse, outsail, parallel run, reverse run, etc.) as described in the Act of Prevention of Collision at

Sea can be readily grasped. If there is a risk of collision with other ship, the operator can determine which rule to be applied and how to operate own ship.

……Radar and Collision Avoidance ……………………………………

Radar is still playing an important roll for collision prevention and positioning. A plotter is used to further enhance the radar functionality. The plotter is capable of plotting other positions of other ships in

3 to 6 minute intervals to monitor their movements. The plots of other ships represent their tracks relative to own ship, and it is shown whether there is a risk of collision, namely CPA and TCPA can be obtained. This method using a plotter is fairly effective, but the number of target ships, which are manually plotted, is limited and it takes several minutes to measure those.

● If the installed indicator is used in an ambient condition of 0º or less, the power to the radar should be turned on more than 60 minutes after the power in the ship is turned on.

● Wait approximately 6 seconds before turning on the power again.

● A malfunction may occur if the power in the ship is instaneously interrupted during operation of the radar. In this case, the power should be turned on again.

● Immediately after the radar is installed, if the system is not used for a long time, or after the magnetron is replaced, warm-up the equipment in the standby mode for 20 to 30 minutes before setting it to the transmit mode.

● If the warm-up time is short, the magnetron may cause sparks, resulting in its unstable oscillation.

Start transmission on a short-pulse range and change the range to the longer pulse ranges in turn.

If the transmission is unstable in the meantime, reset the system to the standby mode immediately and maintain it in the standby mode for 5 to 10 minutes before restart the operation.

Repeat these steps until the operation is stabilized.

PREPARATION

……Tuning TUNE ………………………………………………………

TUNE

This control is used to tune the receiver.

If the receiver is detuned from the best level, the receiving sensitivity falls, and the targets on a long range or the small targets on a short range may be overlooked.

In manual tuning, rotate the [TUNE] control clockwise or counterclockwise and adjust so that the target echoes are the clearest. If no suitable target is present, adjust the control so that the tuning indication bar-graph at the upper left of the radar display is maximized.

After setting the radar to the TRANSMIT mode, it takes about 10 minutes until the oscillation frequency of the magnetron is stabilized. Therefore, tune the receiver once again after about 10 minutes.

For automatic tuning, setting “2.TUNE” to “AUTO” in the AUTO Menu. (Refer to page 3 - 5)

……Sensitivity Control GAIN …………………………………………

GAIN

This control is used to control the radar receiving sensitivity.

Clockwise rotation of the [GAIN] control increases receiving sensitivity and extends the radar observation range. If the sensitivity is too high, the receiver noise will increase to reduce the contrast of the targets with the background video and make the targets obscure on the display. To observe densely crowded targets or the targets on a short range, rotate the [GAIN] control counterclockwise to reduce the sensitivity so that the targets are easy to observe. Be careful not to overlook small and important targets.

……Display Brilliance Control BRILL ………………………………

BRILL

This control is used to adjust the brilliance of the entire display.

Clockwise rotation of the [BRILL] control increases the brilliance of the entire display. Adjust the

[BRILL] control to obtain the best-to-see display with optimum brilliance.

3 – 11

3.3 PREPARATION

……Contrast Control BRILL VIDEO …………………………………

BRILL

VIDEO

The contrast of the radar video display can be adjusted in four levels. Each time the [BRILL VIDEO] switch is pressed, the contrast will change the mode in the following order: / / /

The current mode is indicated at the lower right of the radar display. (The VIDEO indication will

.

change to the PANEL indication in several second.) Adjust the [BRILL VIDEO] switch to obtain the best-to-see video with optimum contrast.

Attention

● In the AUTO SEA mode, there are cases in which the targets are not displayed because the sea clutter returns are suppressed in a simple way.

Use the manual [SEA] control during sailing under normal conditions.

● In the AUTO RAIN mode, there are cases in which the targets are not displayed because the rain/snow clutter returns are suppressed in a simple way.

Use the manual [RAIN] control during sailing under normal conditions.

3

……Sea Clutter Suppression SEA …………………………………

SEA

This control is used to reduce the receiving sensitivity on a short range to suppress the sea clutter returns.

Clockwise rotation of the [SEA] control can suppress sea clutter returns more effectively. Be careful not to suppress sea clutter excessively. Otherwise, small buoys and boats may disappear from the radar display.

When setting 1.SEA/RAIN

When setting 1.SEA/RAIN to to

in the AUTO Menu, the mode is changed into the

AUTO

Note: It is impossible to use both the AUTO SEA mode and the AUTO RAIN mode at the same time.

3 – 12

……Rain/Snow Clutter Suppression RAIN …………………………

RAIN

This control is used to suppress rain or snow clutter returns. Clockwise rotation of the [RAIN] control makes the targets clearer that may be hidden among rain/snow clutter returns. Be careful not to overlook small targets in the clutter. This control also has the effect of reducing sea clutter, so that it is more effective to use this control together with the [SEA] control.

Rotate the control counterclockwise to the maximum in the normal condition.

When setting 1.SEA/RAIN to 3. AUTO RAIN in the AUTO Menu, rain/snow clutter can be suppressed depending upon the intensity level. When setting

AUTO Menu, the mode is changed into the MANUAL mode.

ARPA

The BRILLIANCE switches [PANEL], [BRILL VIDEO] and [BRILL ARPA] are used to adjust the brilliance of the panel, video and ARPA markers. Each time a switch is pressed, the brilliance is increased by one level up to 4 or 5 levels. When the maximum level is reached, the brilliance is reset to the original level.

PANEL Adjusts the lighting for the characters on the controls and switches on the operation panel.

……Degaussing DEGAUSS …………………………………………

Since this radar equipment employs a color CRT, color slip-outs may be caused due to change in the magnetism of the hull structure or the earth magnetism. When turning on the power, the

CRT is automatically degaussed. However, color slip-outs may be caused due to magnetization during radar operation. In this case, it is necessary to degauss the CRT in the following procedures:



9. DEGAUSS will be selected and the CRT will be forcedly degaussed.

If it is insufficient by one time of degaussing, press

9 again after about 30 seconds.

BASIC OPERATIONS

……Move Cross Cursor Mark [ + ] by Trackball ………………………

Trackball

Trackball section right button Trackball section left button

Hand sensor

The cross cursor mark [ + ] is used for position designation and other purposes in various operating procedures. The cross cursor mark [ + ] moves in coupling with the trackball. If the trackball is rotated up and down or left and right, the cross cursor mark follows the move of the trackball. The distance and bearing between own ship and the cross cursor mark [ + ] are indicated on the upper right of the radar display. Before operating other controls and switches, the operator must be familiar with manipulation of the trackball and the move of the cross cursor mark. When rotating the trackball, the cross cursor mark [ + ] will not move if the palm is apart from the hand sensor section. Approach the palm to the hand sensor section and operate the trackball.

True Bearing Mode [NORTH UP]

The video is displayed so that the zenith of the PPI (0

° on range rings) points to the due north.

Fixed targets do not flicker and are easily identified on a chart, and the true bearing of a target can readily be read out.

Relative Bearing Mode [HEAD UP]

The video is displayed so that the ship’s heading line points to the zenith of the PPI (0

° on range rings). Since targets are displayed in their directions relative to the ship’s heading line, the operator can watch the video in the same field of view as in operating the ship at sea.

This mode is suitable for ocean sailing and for watching over other ships.

Course-Up Mode [COURSE UP]

By pressing this switch, the ship’s heading line is fixed pointing to the zenith of the PPI (0

° on range rings). In the same way as in the North-up mode, fixed targets do not flicker, but stabilized even if the ship is yawing. The bearing of the heading line varies by the same shift of own ship’s course. If the course is changed, the heading line can be reset to the Course-up mode by pressing the switch several times.

In the True Motion mode, the position of own ship on the display moves depending upon its course and speed and the influence of the current. Land and other fixed targets are fixed on the display and only actually moving targets move on the radar display. When the True Motion mode is selected, own ship’s position will be set to about 60% of the display radius in the opposite direction to its course allowing for the influence of the current.

Own ship will start moving depending upon its course and speed and the influence of the tide.

Subsequently, when own ship arrives at the position of about 65% of the display radius, the ship will be automatically reset to its initial position at about 60% of the display radius in the opposite direction to its course allowing for the influence of the current.

In making up any navigational information, it is necessary to set up the geodetic system used by the connected navigation equipment. When any saved navigational information is loaded, the geodetic system used when the navigational information was saved will also be displayed. Then, check that the geodetic system on display is the same as that for the connected navigation equipment. If both geodetic systems are different, the positions of the navigational information on radar display may be deviated. Therefore, it is important to set the same geodetic system as the navigation equipment.

Attention

There are the following limitations on use of the target acquisition and tracking functions of ARPA:

Use these radar only as assisting device for navigation.

The final decision for navigation should made by the officer himself.

[ 1 ] Resolution between adjacent targets and swapping during automatic tracking

Depending on the particular distance and echo size, resolution between adjacent targets during automatic tracking usually ranges somewhere between 0.03 to 0.05 nm. If multiple targets approach each other, resolution will become about 0.03 nm and this may cause the system to regard them as one target and thus to swap them or lose part of them. Such swapping or less of targets may also occur if the picture of the target being tracked is affected by rain/snow clutter returns or sea clutter returns or moves very close to land.

[ 2 ] Intensity of echoes and the tracking function

The intensity of echoes and the tracking function have a correlationship, and thus the target will be lost if no echoes are detected during six scans in succession.If a lost target exists, therefore, radar gain must be increased to support detection of the target.

If, however, radar gain is increased too significantly, sea clutter returns or other noise may be erroneously detected and tracked as a target, and resultingly, a false alarm may be issued. In such a case, radar gain must be reduced to suppress the noise.

[ 3 ] Adverse effects of error sources on automatic tracking

To execute accurate tracking, it becomes necessary first to appropriately adjust the

[GAIN], [SEA] and [RAIN] controls of the radar so that the target to be acquired and tracked is clearly displayed. Inappropriate settings of these controls reduce the reliability/accuracy of automatic tracking.

TARGET ACQUISITION

Attention

● It is important to adjust the controls [SEA] and [GAIN] properly in the automatic target acquisition mode to minimize sea clutter returns acquired falsely.

Target acquisition can be performed on two modes, AUTO and MANUAL, and both modes can be used at the same time.

……Automatic Acquisition AUTO ……………………………………

Attention

● If untracked targets intrude into the guard zone in the conditions that the maximum number of targets (50 targets) are under tracking, the targets acquired automatically will be cancelled in the order of lower levels of danger.

Procedures

ACQ

AUTO

The automatic target acquisition will start. The target acquired will be marked with “ ” and its target ID No., which will move with the target. Its vector will appear within one minute.

Note: When Target ID No. Display is set to OFF, any captured target ship will not be attached with its target ID No.

In the ACQ AUTO mode, the targets within a guard zone will be acquired automatically. The guard zone can be set arbitrarily. If a guard zone is not set, a guard zone of 3 NM and ±45˚ in the direction of own ship will be set. (Guard Zone 1: heading direction, Guard Zone 2: sternward direction)

For the setting method, refer to section 3.4 “Set Guard Zones”.

ARPA DATA DISPLAY

(Refer to Example of Display in page 2-1.)

……Display of Vectors ……………………………………………………

Attention

● When a target or own ship changes a course, or when a target is acquired, its vector may not reach a given level of accuracy until three minutes or more has passed after such course change or target acquisition.

Even if three minutes or more has passed, the vector may include an error depending upon the tracking conditions.

A vector to represent a target’s predicted position can be presented in the TRUE vector or RELATIVE vector mode. In each mode, a vector length can be freely changed for a time interval of 1 to 60 minutes.

[ 1 ] Vector Mode Selection

True Vector Mode

In the true vector mode, the direction of a target vector indicates the true course of the target and its vector length is proportional to its speed.

In this mode, own ship’s vector is displayed as shown below.

In this mode, the movements of other ships around own ship can be accurately and easily monitored.

However, no CPA RING can appear in this mode.

5

5 – 14

Relative Vector Mode

In displaying the relative vector of a target, press the [TRUE/REL] switch to select the Relative Vector mode.

The relative vector does not represent the true motion of the target, but its relative relation with own ship. This means that a target with its relative vector directed to own ship (passing through the CPA

LIMIT ring) will be a dangerous target.

In the Relative Vector mode, it can be seen at a glance where the CPA LIMIT of the dangerous target is.

Therefore, the TRUE/REL mode shall optionally be used for the purpose of observation: the TRUE vector mode for grasping the true aspect of a target, and the REL vector mode for grasping a target’s closest point of approach (CPA).

5 – 15


[ 2 ] Vector Length: VECTOR TIME

The vector length of a target is proportional to its speed, and the vector time can be changed over in a range of 1 to 60 minutes by used for ten-key.

The diagram below illustrates a vector length of a target for six minutes, and the tip of the vector represents the target’s position expected to reach six minutes later.

CAUTION

In setting a guard zone, it is necessary to adjust the radar tune, gain, sea clutter suppression and rain/snow clutter suppression to ensure that target echoes are displayed in the optimum conditions. The guard zone alarm is not generated against the targets that are not detected by radar.

The guard zone functions are to set a zone at an arbitrary range and to deliver an alarm if any target intrudes within this zone.

For the method of setting a guard zone, refer to section 3.4 “Set Guard Zones”.

● If the radar tuning, gain, sea clutter suppression, rain/snow clutter suppression are not adjusted adequately, the lost target alarm may be easily generated. So such adjustments should be mad carefully.

When it is impossible to continue tracking any acquired and tracked target, the LOST target alarm will be generated. The typical causes for alarm generation are shown below, but not limited to the following:

• The target echo is very weak.

• The target is shadowed by a shore or a large ship and its echo is not received.

• The target echo is blurred by sea clutter returns.

When an abnormal state of an input signal or a trouble in the processing circuitry occurs, an character or alarm is generated. When an alarm occurs against any ARPA function, ARPA (DATA) will appear in the WARNING display area, but no indication is made in the ARPA information display. This status means that there is any operational trouble in the ARPA system. Please, contact the service depot or the manufacturer.

……Gyro Set Alarm SET GYRO ………………………………………

The North Stabilizing Kit (NSK) in this system receives signals from a gyro. Even if the power is turned off, the system will follow up the gyro. However, the system stops the follow-up operation when the power of the master gyro is turned off or when any trouble occurs to the line. When the power of the master gyro is recovered, the SET GYRO alarm will be generated.

If this alarm occurs, set the gyro.

TRIAL MANEUVERING

Attention

● Trial maneuvering is to simulate own ship’s course and speed in the conditions that the course and speed of a target ship are unchanged as they are. As the situation is different from any actual ship maneuvering, set values with large margins to CPA LIMIT and TCPA LIMIT.

The trial maneuvering is the function of simulating own ship’s course and speed for collision avoidance when a dangerous target appears. When manually entering own ship’s course and speed against the data of the acquired target, it is checked whether the situation is dangerous or not.

The ranges of course and speed to be entered manually:

Course: 360˚ (in 0.1˚ intervals) …………………………[EBL] control

Velocity: 0 to 100 knots (in 0.1 knot steps) ………………[VRM] control

……Trial Maneuvering in the True Vector Mode ………………………

In the True Vector mode, calculations are performed according to the values set by TRIAL SPEED and

TRIAL COURSE, and the result is displayed as a bold-line that represents the change of own ship’s vector as shown in the figure below (an example of the course changed to the right).

In this figure, the dangerous target forward right becomes safe as a result of simulation.

The target data display field indicates the current CPA LIMIT and TCPA LIMIT values regardless of the result of simulation.

5 – 27

5.8 TRIAL MANEUVERING

……Trial Maneuvering in the Relative Vector Mode …………………

The result of trial maneuvering in the Relative Vector mode is shown by a change in target vector. In the figure below (in the same conditions as in the True Vector mode in the previous page), it is seen that the acquired target is a dangerous one because its vector is crossing the CPA RING.

The above figure shows that the relative vector of the target has changed as shown in the figure as a result of simulation (course and speed), so that the target’s symbol is changed into “ ”, a safe target.

The data display field indicates the current values of CPA LIMIT and TCPA LIMIT, not those as the result of simulation, same as in the True Vector mode.

The course change of own ship is displayed as a dotted-line.

ARPA SETTING

CAUTION

Simulation is a function to check whether the ARPA system is operating normally. Do not use this function except when checking the ARPA operation.

In particular, if this mode is used during navigation, pseudo targets appear on the radar display, which may be confused with the actual targets. Do not use this mode during navigation.

Otherwise, this may cause accidents to occur.

The following constants to be used for ARPA can be referred to and modified:

[ 1 ] SIMULATOR

[ 2 ] VD LEVEL

[ 3 ] VECTOR CONSTANT

[ 4 ] GATE

[ 5 ] TEST VIDEO

: Pseudo targets are generated on the radar display to check whether the ARPA functions are operating normally.

: Quantizing level for the video to be inputted to the target detection circuit.

: Constant to calculate the ARPA vectors.

: Gate size to acquire and track targets.

: Test video for use in checking the operation of the target detection circuit.

Each of the constants will be described in detail below.

5 – 32

……Simulation ………………………………………………………………

CAUTION

Do not change VD LEVEL and VECTOR CONSTANT carelessly because those are set to the optimum values. Otherwise, this may deteriorate the ARPA performance and cause accidents to occur.

Pseudo targets can be generated in certain known positions to check whether the ARPA processing circuits are operating normally. Since the pseudo targets move depending on known parameters, the values for these pseudo targets can be compared with the known values if the pseudo targets are acquired and tracked, and displayed. Thus, it can be checked if the ARPA system is operating normally.

This function should be operated only in the standby mode.

CAUTION

Do not change the preset gate size carelessly. If the gate value is improper, the ARPA acquisition and tracking functions may deteriorate.


The Gate Size is defined as an “Area within which targets are watched by the ARPA” processing circuit.

If the gate size is too large, targets are not lost but may be swapped with other close targets.

If the gate size is too small, targets are not easily swapped, but may be lost.

The ARPA processing circuit is designed to detect target sizes and set an accurate gate size depending on the ranges and sizes of those targets (NARROW is the standard size). However, change the setting parameters to select the best size in the following conditions:

Set 2. NARROW in normal operation.

• When acquiring and tracking targets that spread widely in the angular direction

(The angular direction of the gate aperture is important) ………………………………… 1. WIDE

• When many targets are densely congested and swapped within 3 NM in a port

(The gate size should be reduced) ……………………………………………………… 3. SMALL

The radar operator has a role of interpreting the radar displays to provide his best aid in maneuvering the ship. For this purpose, the operator has to observe the radar displays after fully understanding the advantages and disadvantages that the radar has. For better interpretation of radar displays, it is important to gain more experiences by operating the radar equipment in fair weathers and comparing the target ships watched with the naked eyes and their echoes on the radar display.

The radar is mainly used to monitor the courses of own ship and other ships in open seas, to check buoys and other nautical marks when entering a port, to measure own ship’s position in the coastal waters relative to the bearings and ranges of the shore or islands using a chart, and to monitor the position and movement of a heavy rain if it appears on the radar display.

Various types of radar display will be explained below.

……Radar Wave with the Holizon ………………………………………

Radar beam radiation has the nature of propagating nearly along the curved surface of the earth.

The propagation varies with the property of the air layer through which the radar beam propagates.

In the normal propagation, the distance (D) of the radar wave to the horizon is approximately 10% longer than the distance to the optical horizon. The distance (D) is given by the following formula:

D = 2.23 ( h 1 + h 2 ) (nm) h1: Height (m) of radar scanner above sea level h2: Height (m) of a target above sea level

Fig.6.1 is a diagram for determining the maximum detection range of a target that is limited by the curve of the earth surface in the normal propagation.

6 – 1

Radar Wave with the Holizon

...

.

Fig.6.1

When the height of own ship’s scanner is 10 m for instance,

(a) A target that can be detected at the radar range of 64 nm on the radar display is required to have a height of 660 m or more.

(b) If the height of a target is 10 m, the radar range has to be approx. 15 nm. However, the maximum radar range at which a target can be detected on the radar display depends upon the size of the target and the weather conditions, that is, the radar range may increase or decrease depending upon those conditions.

6

6 – 2

……Strength of Reflection from the Targets …………………………

The signal intensity reflected from a target depends not only on the height and size of the target but also on its material and shape. The echo intensity from a higher and larger target is not always higher in general.

In particular, the echo from a coast line is affected by the geographic conditions of the coast.

If the coast has a very gentle slop, the echo from a mountain on the inland appears on the radar display.

Therefore, the distance to the coast line should be measured carefully.

Fig.6.2

……Sea Clutters ……………………………………………………………

When the sea surface ruffles, bright echo returns spread around the center of the radar display.

The higher the waves are, the echo returns are larger.

Swirling currents may appear as a smooth line like a coastal line.

……False Echoes …………………………………………………………

The radar observer may be embarrassed with some echoes that do not exist actually. These false echoes appear by the following causes that are well known:

[ 1 ] Shadow

When the radar scanner is installed near a funnel or mast, the echo of a target that exists in the direction of the funnel or mast cannot appear on the radar display because the radar beam is reflected on the funnel or mast. Whether there are some false echoes due to shadows can be checked by monitoring the sea clutter returns, in which there may be a part of weak or no returns.

Such shadows appear always in the same directions, which the operator should have in mind in radar operation.

6 – 3

False Echoes

...

.

[ 2 ] Side Lobe Effect

A broken-line circular arc may appear at the same range as the main lobe of the radar beam on the radar display. This type of false echo can easily be discriminated when a target echo appears isolated. (See

Fig.6.3)

Fig.6.3

[ 3 ] False Echo by Secondary Reflection

When a target exists near own ship, two echoes from the single target may appear on the radar display.

One of those echoes is the direct echo return from the target and the other is the secondary reflection return from a mast or funnel that stands in the same direction as shown in Fig.6.4.

Fig.6.4

[ 4 ] False Echo by Multiple Reflection

When there is a large structure or ship with a high vertical surface near own ship as shown in Fig.6.5, multiple reflection returns may appear on the radar display. These echoes appear in the same intervals, of which the nearest echo is the true echo of the target.

HL

6

Fig.6.5

6 – 4

[ 5 ] Abnormal Propagation

The maximum radar detection range depends upon the height of the scanner and the height of a target as described in the section of “The Horizon for Radar Beam Radiation”. If a so-called “duct” occurs on the sea surface due to a certain weather condition, however, the radar beam may propagate to a abnormally long distance, at which a target may be detected by the radar.

For instance, assuming that the radar range is 6 NM (on the repetition frequency of 1100 Hz), the first pulse is reflected from a target at about 76 NM or more and received during the next pulse repetition time. In this case, a false echo appears at a position that is about 76 NM shorter than the actual distance.

If the false echo appears at 5 NM on the radar display, the true distance of the target is 5 + 76 = 81 NM.

On the radar range scale of 1.5 NM (on the repetition frequency of 1900 Hz), a false echo may appear at a position that is about 43 NM shorter than the actual distance.

This type of false echo can be discriminated by changing over the range scale (the repetition frequency), because the distance of the target changes accordingly.

[ 6 ] Radar Interference

When another radar equipment using the same frequency band as that on own ship is near own ship, a radar interference pattern may appear on the radar display. This interference pattern consists of a number of spots which appear in various forms. These spots do not always appear at the same places, so that they can be discriminated from the target echoes. (See Fig.6.6)

Fig.6.6

6 – 5

Display of Radar Transponder (SART)

...

.

……Display of Radar Transponder (SART) ……………………………

The SART (Search and rescue Radar Transponder) is a survival device authorized by the GMDSS

(Global Maritime Distress and Safety System), which is used for locating survivors in case that a distress accident occurs at sea. The SART is designed to operate in the 9 GHz frequency band.

When receiving the 9 GHz radar signal (interrogating signal) transmitted from the radar equipment on a rescue ship or search aircraft, the SART transmit a series of response signals to inform the distress position to the rescue and search party.

The SART position can be displayed on the radar video by setting the radar as follows: q Radar range scale : 6 NM or 12 NM w Sea clutter control e AUTO SEA function

: Minimum (Most counterclockwise)

: OFF r TUNE control : No tuning (to weaken clutter echoes) t Interference rejector (IR) : OFF y PROCESS : OFF

6

[Example of Display]

Attention

● When the radar is set as in q to y above to detect the SART signal, the targets around own ship will disappear from the radar display. So it is necessary to exercise full surveillance over the conditions around own ship by visual watch in order to avoid any collision or stranding.

If two or more sets of radar equipment are installed on own ship, use one set of 9 GHz band radar for detection of the SART signal and operate others as normal radars for monitoring targets around own ship, checking on own ship’s position and avoidance of stranding.

After end of detecting the SART signal, it is necessary to readjust the radar for normal navigation.

WARNING

Turn off the main power source before starting maintenance.

Otherwise, an electric shock or injury may result.

Set the Safety Switch for Stopping the Scanner to cents OFF .

Otherwise, an accidental contact with the rotating scanner may result in injury.

After finishing the maintenance work, set the safety switch for stopping the scanner to “ON”.

Precautions on Mounting the Cover

When the cover is removed for regular checkup and replacement of parts and refitted after such work, the procedures of fastening bolts shall be taken with the following precautions:

(a) The proper fastening torque of the fitting bolts (M8) is 1176 to 1470 N•cm (120 to 150 kgf•cm) (which makes the inside water-tight and protects the packings against permanent compressive strain).

The packings start producing from the cover at the torque of approximately 1470N•cm (150 kgf • cm) or more.

Do not fasten the bolts with a torque exceeding the specified value. Otherwise, the screws may be broken.

(b) Use an offset wrench of 11 mm

×

13 mm or a double-ended wrench of 13 mm

×

17 mm (not longer than 200 mm).

(c) Screw all the bolts by hand first to prevent them playing, then fasten them evenly in 4 to 5 steps to reach the final torque in accordance with the fastening procedures in order not to cause one-sided fastening. (Fasten the bolts with 25% of the required torque at the first step.)

*: Fasten the bolts in the diagonal order.

Attention

● If the radiator front face (radiation plane) is soiled with smoke, salt, dust, paint or birds’ droppings, wipe it with a piece of soft cloth wetted with alcohol or water and try to keep it clean at all times. Otherwise, radar beam radiation may attenuate or reflect on it, resulting in deterioration of radar performance.

● Never use solvents of gasoline, benzine, trichloroethylene and ketone for cleaning. Otherwise, the radiation plane may deteriorate.

Check up and clean the radiator.

.

(2) Scanner Mechanism a) Supply Oil Seal

When there is not a grease nipple, the replenishment of grease oil is unnecessary.

Remove the cap of the grease nipple on the front of the S band radiator support and supply it with a grease gun. Make the oiling every six months. The oil quantity shall be approximately

100 g that is as much as the grease comes out of the oil seal. Use the grease of Mobilux 2 of

Mobil Oil.

(b) Oiling gears

Apply grease evenly to the tooth surfaces of the main shaft drive gear and the encoder drive gear with a spreader or brush. Greasing in short intervals is more effective to prevent the gears from wear and tear and extend their service life, but grease those at least every six months.

Use Mobilux2 of Mobile Oil.

(c) Mounting legs

Check the mounting legs and mounting bolts of the scanner unit case on corrosion sometimes and keep them in order not to cause any danger. Apply paint to them once a half year because painting is the best measure against corrosion.

TROUBLESHOOTING

In case of semiconductor circuits, it is deemed that there is few cases in which the used semiconductor devices have inferior quality or performance deterioration except due to insufficient design or inspection or by other external and artificial causes. In general, the relatively many causes are disconnection in a high-value resistor due to moisture, a defective variable resistor and poor contact of a switch or relay.

Some troubles are caused by defective parts, imperfect adjustment (such as tuning adjustment) or insufficient service (such as poor cable contact). It will also be effective to check and readjust these points.

Melted fuses are caused by any clear cause. When a fuse is replaced, it is necessary to check the related circuits even if there is no trouble. In this case, note that there is some dispersion in the fusing characteristics. Table 8.7 shows a list of fuses used in the equipment.

REPLACEMENT OF MAJOR PARTS

CAUTION

Turn off the main power source before replacing parts.Otherwise, an electric shock or injury may result.

Before replacing the magnetron, turn off the main power source and wait for 5 minutes or more until the high voltage circuits are discharged.

Otherwise, an electric shock may result.

Take off your wrist watch when bringing your hands close to the magnetron.

Otherwise, your watch may be damaged because the magnetron is a strong magnet.

Two or more persons shall replace the CRT.

If only one person does this work, he may drop the CRT, resulting in injury.

Even after the main power source is turned off, some high voltages remain for a while.

When disconnecting the wires of the high-voltage pack from the CRT, do not contact the core wire (metallic) of the CRT anode cap with bare hands. Otherwise, an electric shock may result.

……Replacement of Magnetron (V1/V101/V201)………………………

Remove the shield cover of the modulator and check that no charge remains in the high-voltage modulator circuit. Then, remove the socket of the magnetron. The magnetron can be demounted by removing the screws fixing it. When mounting a new magnetron, do not touch the magnet with a screwdriver or put it on an iron plate. After replacement, connect the lead wire correctly.

Handling of Magnetron under Long-Time Storage

The magnetron that has been kept in storage for a long time may cause sparks and operate unstably when its operation is started. Perform the aging in the following procedures:

(1) Warm up the cathode for a longer time than usually. (20 to 30 minutes in the STBY state.)

(2) Start the operation from the short pulse range and shift it gradually to the longer pulse ranges. If the operation becomes unstable during this process, return it to the standby mode immediately.

Keep the state for 5 to 10 minutes until the operation is restarted.

(3) After transmission is made for about 15 minutes, conduct the tuning adjustment.

(4) Adjust RV1 within the receiver so that the bar graph of the tuning indicator on the display reaches the reading 10 without saturation.

……Quantization Level ……………………………………………………

CAUTION

Do not change the set quantization level carelessly. If the level deviates from the proper value, the ARPA acquisition and tracking functions will deteriorate.


The quantization level determines the minimum signal level of the input video to the ARPA target detection circuit. In this test, the value of the quantization level can be set in a range of 1 to 63.

If the value is set to a lower level, weak target echoes will be inputted to the ARPA target detection circuit, but much radar noise will also be inputted to the circuit together, and target acquisition and tracking may be disabled. Therefore, it is important to set a value that is 4 or 5 higher than the detected noise level.

……Main Bang Suppression Adjustment………………………………

This adjustment is intended for suppressing the main bang that is an echo signal from the microwave circuit such as waveguide appearing as a circular echo at the radar video center. It is the optimum level in which the main bang suppression is adjusted so that the main bang remains weak on the video.

Attention

● Do not change the adjusted level carelessly. If the adjustment is improper, the target signals on the short ranges may be cleared.

Procedures 1 Set the radar range scale to the minimum 0.125 NM, set PROCESS, TGT ENH and

FUNCTION to OFF, and set the system to the Transmit mode.

2 Adjust the operation controls as follows:

[GAIN] control: Maximum

[SEA] control: Middle (MANUAL)

1. GENERAL

1.1 Outline

The Interswitch Kit enables all possible interconnections between two or more radar display units and two or more scanner units installed on the bridge of a ship that have different characteristics.

The NQE-3015N Interswitch Kit is used for the JMA-9800 series radar system and it is capable of switching over interconnections between three display units and three transmitter-receiver/scanner units

(hereinafter called “MTR”).

1.2 Interswitch Construction

The Interswitch Kit is incorporated in the display unit. (Option)

The number of combined display units and MTRs according to the interswitch kit is different between the 2-units system and the 3-units system.

The distinction between the 2-units system and the 3-units system is determined by the internal settings.

The pattern switchover operations can be exercised simply and quickly according to the menus displayed on the display unit. The interswitch patterns as shown below are displayed at the upper left of the radar display. (The position filled on the mark indicates the position of the display unit currently operated.)

REFERENCES

Pre-heat Time after Pattern Selection

After switching over the interswitch patterns, it is necessary to wait for the time as mentioned below because the pre-heat time is different from the previous interconnection between the MTR and the display unit. This measure is taken for protecting the electronic tube emitting radar pulses.

(a) Not changed to the new interconnection condition:.............................No preheat time

(b) Changed to the new interconnection condition.

However, the MTR was used before change: ..............................................30 seconds

(c) Changed to the new interconnection condition.

However, the MTR was not used before change: ..........................................3 minutes

Notes on Pattern Selection

Immediately after switching over the patterns, the try to select another pattern may fail. This means that even If the pattern switchover is completed, it takes some time to prepare for the next interswitch operation. In this case, “ISW BUSY” will be indicated in the message area on the display lower right, and the interswitch operation is not available.

Alarm Sound Control

The interswitch alarm continues to sound for about 5 seconds. In setting the alarm sound level, open the Sub1 Menu, press [2] switch to select the “5.BUZZER” in LEVEL Menu. (Refer to page

3 - 61)

When stopping the alarm sound immediately after it sounds, press [ALARM ACK] switch. Even when the alarm sound stops, a certain message will remain in the message area.

Notes on Master/Slave Connection

The Master/Slave connection is a configuration in which the Display Unit connected to the Scanner

Unit is the Master Unit, while the Display Unit connected to the Master Unit is a Slave Unit. Of the interswitch patterns, the following pattern numbers includes the Master/Slave connection: a) 2-unit System: No.3, No.4, No.5 and No.6

b) 3-unit System: No.4, No.5, No.6, No.7, No.8, No.9, No.10 and No.11

If the Master Display Unit is not in the transmission state, it is impossible to set the Slave Display

Unit to the transmission state. If the Master Display Unit is changed from the transmission to the standby mode, the Slave Display Unit will also be set to the standby mode forcibly. In this status,

“MTR ST-BY” will be indicated in the message area and the alarm will beep.

A – 19

The Slave Display Unit will not change the radar video even if the tuning control is adjusted because the tuning is controlled by the Master Display Unit. The tuning indicator at the upper left of the display will show “SLAVE”.

The change of the range scale on the Slave Display Unit depends upon the range scale on the

Master Display Unit. In general, the Slave Display Unit can not change the range scale into a higher one than that on the Master Display Unit. However, a higher range scale may be selected by the Slave Display Unit if the pulse length/repetition frequency is the same as on the Master Display

Scanner Safety Switch

If the Scanner Units are changed over in the condition that the safety switch of one Scanner Unit is set to “OFF” while the other is set to “ON”, “SSW OFF” will be indicated on both the display.
