SECTION 1:

OVERVIEW

The 3300-HM Full Spectrum Sonar is a versatile, wideband, FM sub-bottom profiler that generates crosssectional images of the seabed and collects digital normal incidence reflection data over many frequency ranges.

The system transmits an FM pulse that is linearly swept over a full spectrum frequency range (also called a “CHIRP pulse”). The reflections, measured by the system, are displayed as shades of gray or color on a computer monitor. Data is stored real-time into a large capacity hard drive, and can be archived to a

CD/DVD ROM or thumb drive.

1.1 Advantages of Full Spectrum CHIRP Technology

EdgeTech’s Full Spectrum Technology has several distinct advantages over conventional sub-bottom systems, including increased penetration and higher resolution. The tapered wave form spectrum results in images that have virtually constant resolution with depth.

The 3300 system also generates virtually no side lobes due to the wide bandwidth of the sweep frequency.

This bandwidth has an effect of smearing the side lobes of the transducer, resulting in a beam pattern with almost no side lobes.

Because the FM pulse is generated by a digital-to-analog converter with a wide dynamic range and a transmitter with linear components, the energy, amplitude, and phase characteristics of the acoustic pulse can be precisely controlled. This precision produces the high repeatability and signal definition required for sediment classification.

The frequency range of operation is determined by the acoustic characteristics and mounting schematic of the transducers. EdgeTech offers various transducer configurations that can transmit acoustic pulses with different center frequencies and bandwidths. Pulse selection is made by the operator while profiling to achieve the best imagery. For detailed information regarding configuration options, contact

1.1.1 Compared to Older Technology

EdgeTech’s 3300 Full Spectrum sonar system transmits FM pulses. FM pulses have been used in radar and sonar systems for over 40 years and are sometimes referred to as CHIRP or swept frequency pulses. The advent of modern digital signal processing components has provided tools for realizing the potential of these methods.

Full Spectrum signal processing technology does not use a conventional matched filter (the correlation filter that is widely used to compress FM signals) to process wide band signals. It uses proprietary amplitude and phase weighting functions for the transmitted pulse and a pulse compression filter that maximizes the signal-to-noise ratio (SNR) of the acoustic images over a wide band of operating frequencies. These functions provide a significant SNR improvement in the acoustic image over other impulse and CHIRP sonar with band-limited components that are limited in dynamic range.

1-2 SECTION 1: OVERVIEW

1.1.2 Transducer Array

The acoustic projectors in the 3300 Hull Mount system are constructed from wideband, piston-type transducers and the acoustic receivers are a discrete line array of PZT crystals. The acoustic transducers mounted in the hull of the ship are designed for profiling at ship speeds varying from zero (drifting) to 7 knots.

The transducer array receives the low amplitude sub-bottom reflections, while a 24-dB gain preamplifier amplifies and drives the signal through a 50-meter cable. A software-controlled, programmable gain amplifier provides a final amplification stage before the signal is digitized with a 16-bit Analog-to-Digital

(A/D) converter at a sampling rate of 24, 40, 50, and 66 kHz. To achieve the theoretical temporal resolution predicted by the inverse of the bandwidth, the FM pulse is compressed using a digital compression filter.

The correlation process is implemented in real-time, with forward and inverse Fast Fourier Transforms.

The compressed pulse resulting from this signal processing procedure has a time duration approximately equal to the inverse of the bandwidth of the FM pulse.

1.1.3 Resolution

High temporal resolution allows for the measurement of fine layering. Good resolution is an important factor in sediment classification, as it provides a more precise impulse response of the sediment, and, in turn, a realistic picture of the true geologic variability of the seafloor and accurate determination of the depositional processes. When the time duration of the processed pulse is too large, individual reflections will be lumped together with random phase causing constructive and destructive interference, thereby making it difficult to estimate the impedance and examine the geologic processes.

1.1.4 Processing Enhancements

In addition to the resolution improvement, correlation processing achieves a signal processing gain over the background noise. This gain is approximately ten times the log of the time-bandwidth product. This improvement is due to the signal having a time duration longer than the inverse of the bandwidth, thus increasing signal energy without increasing the power of the outgoing pulse. To equal the typical performance of the Full Spectrum sonar pulse, conventional pulse sonar would have to operate at a peak pulse power of 100 times greater than the Full Spectrum pulse with a time-bandwidth product of 100.

Another important feature of the Full Spectrum Sub Bottom Sonar is that the computer generates a signal that optimizes the performance of the system. The sonar contains many components, each with a unique dynamic range and linearity characteristic, which are frequency dependent.

In addition to this, the amplitude spectrum of the outgoing pulse is chosen to be approximately Gaussian in shape in order to limit the side lobe level and temporal resolution losses due to attenuation. As a wavelet with a Gaussian-shaped spectrum is attenuated by the sediment, energy is lost but its bandwidth


1-3

is nearly preserved. Thus, even after being attenuated by sand, the acoustic pulse has approximately the same resolution as an un-attenuated pulse.

1.1.5 Reduction of Side Lobes and High Repeatability

Full Spectrum sonar has the unique ability to reduce side lobes in the effective transducer aperture. The wide bandwidth of the sweep frequency has the effect of smearing the side lobes of the transducer and thus achieving a beam pattern with virtually no side lobes. The effective spatial beam width obtained after processing the 2-10 kHz signal is 20 degrees measured to -3db points.

Since the transmitted Full Spectrum pulse is highly repeatable, and its peak amplitude is precisely known, the sediment reflectivity values can be estimated from the peak pulse amplitude measurements of the bottom returns.

1.2 Major Components

The hull mounted configuration consists of the topside unit, deck cable, T-R box, spider box assembly, and

the transducer arrays (see an example of a 2x2 system configuration is shown in

Figure 1-1

1.2.1 Deck Unit

The Deck Unit consists of a processor, amplifier, and monitor (see

Figure 1-2

). The enclosure consists of a

computer-based controller containing a Sonar Interface Board (SIB). The SIB stores the transmitted waveform and the correlation filter, and performs the correlation processing and spherical range correction. At periodic intervals, the SIB sends the transmitted waveform to the 16-bit digital-to-analog converter, which generates an analog pilot signal that is amplified by a 2 kW power amplifier. This amplifier drives the transducer.

The acoustic signal returns from the seafloor are measured by the receiving arrays, and are then increased by a preamplifier. The output of the preamplifier is connected via the underwater signal cable to a digitally-controlled amplifier on the sub-bottom board (mounted on the SIB) before being sampled by a

16-bit analog-to-digital converter. The SIB board performs the correlation processing, corrects for spherical spreading, and transfers the data to the system board.

The DISCOVER Sub-Bottom program is supported under Windows 7 operating systems. The data and control connections to the DISCOVER Sub-Bottom program are entirely through TCP/IP connections.

EdgeTech’s Full Spectrum sonar systems employ advanced CHIRP technology to obtain high resolution, low-noise data records. EdgeTech’s advanced CHIRP technology employs long-duration, wide-band, frequency-modulated transmit pulses. Return sonar echo data is processed to remove the FM carrier, and produce high-resolution images of the echo field. DISCOVER Sub-Bottom allows monitoring of this normal, de-CHIRPed, sub-bottom data, as well as raw, CHIRPed data. This latter data type is often useful for diagnostic purposes.

For compatibility with other EdgeTech products, the DISCOVER Sub-Bottom program interfaces to a second program that is run in the background called sonar.exe. Sonar.exe interfaces with both the SIB and the analog interface boards to generate and transmit CHIRP pulses. A startup file launches the sonar.exe program automatically every time the system is booted.

The 3300 Hull Mount topside unit also interfaces with navigation, triggers, motion and heave sensors, echo sounder, and printers.

The computer-based controller and amplifier components of the 3300 Hull Mount are mounted in a rugged case. Alternatively, these modules may be removed from case and installed in a 19" rack.

1.2.2 Interface Box

1.2.3 Transducer Array

The transducers for the 3300 Hull Mount system are mounted in a two-dimensional array inside a closed well on board a survey vessel. These transducers act as both projectors and hydrophones.

EdgeTech offers a range of transducer arrays, each designed to provide various beam width. In general, lower operating frequencies require multiple receiving arrays and larger transducers, therefore requiring different array sizes.

2.1.2 Amplifier Specifications

The amplifier is also designed for mounting in standard equipment rack. The power amplifier must stay close to the topside processor due to the short cables that connect the two units. The amplifier also requires at least 10 cm (4 in.) of clearance behind the heat sink array to permit vertical air flow through the array. Ensure that the environmental operating temperature ion the rack mount does not exceed 55°

C (131° F).

NOTE:

Should overheating occur because of inadequate ventilation, thermal protection circuit will automatically protect the amplifier. When a safe operating temperature is restored, the amplifier will resume normal operation.

NOTE 1:

Vertical resolution is the smallest distinguishable distance between the peaks of two reflections that can be displayed on the screen as separate reflectors. Sound energy is reflected back to the sonar system when the transmitted pulse encounters a change in density, and the resolution of a sonar system is measured by its ability to distinguish between two adjacent targets. The vertical resolution is dependent of the transmitted chirp pulse bandwidth. It is theoretically calculated by the product of the transmitted pulse length (inverse of the bandwidth) and half the speed of sound in water (approximately 750m/s).

NOTE 2:

The value for sub-bottom penetration is the maximum distance beneath the sea floor that a step change of 10% in density can be seen on the sub-bottom display. This assumes that the sediment is gas-free (no organic materials), and that the lowest frequency of the pulse spectrum is transmitted. Lower frequencies reduce attenuation (absorption of sound).

NOTE 3:

Many factors contribute to the penetration performance of a

Hull Mounted system. However, one of the essential factors in determining the performance of a chirp pulse, along with the expected penetration and resolution, is the center frequency of the chirp pulse?

Therefore, for example if you have a pulse of 1-8 kHz then you use the center frequency (4.5 kHz) to determine resolution and penetration.

Another contributing factor is the size of the array. The low frequency efficiency goes up as you increase the size of the array because of increased directivity.

Figure 2-5 : KT-106 Non-Symmetrical Array Configurations

2.3.1 Array Sizes

Selection of array size depends on transducer type (KT-216 or KT-106) and the geological survey application. The important decision parameter is the water depth in which the system is to be used. For most deployments to 3000 meters, a 4 x 4 array will provide the needed performance. A 2 x 2 array should be considered only for coastal application and water depths to 300 meters. Only a 5 x 5 array can be used for full ocean depth.

The following is a matrix of Signal to Noise Ratio for each array size. It assumes sea state 5, flow noise of

70 dB (about a 10-knot speed), a loss in typical seafloor sediments of 10 dB, a 20 ms pulse length, and a bandwidth of 5 kHz. Several other variables are not included in this matrix. They include hull type and thickness, self-noise, variations in flow noise, other ship’s speeds, other sea states, and roll and pitch. Nor does it consider other conditions that could affect the performance, such as a bubble screen.

Table 2-9: Array Size vs. Expected Signal-to-Noise Ratio (SNR)


NOTE:

The 2-way transmission coefficient for a 4 kHz center frequency over a 0.5 inch steel acoustic window is 0.5 (i.e. 50% of the acoustic pulse amplitude is lost due to the 2-way travel of sound through the plate). The coefficient reduces with higher frequencies and thicker steel hull.

INSTALLATION

This section explains how to unpack, inspect, and install the 3300-HM system .It describes placement considerations for the topside and transducer arrays, along with power requirements. Refer to the PN

0016695 for a more detailed explanation of 3300-HM installation.

For information on connecting a navigation device or printer, please refer to

APPENDIX B: NAVIGATION

SYSTEMS

.

4.1 Unpacking & Inspecting

The EdgeTech 3300-HM system is supplied complete with all necessary cables. The system components are individually packed in reusable shipping containers.

Before unpacking the system components, inspect the shipping containers for any damage. Report any damage to the carrier and to EdgeTech Customer Service. If the shipping containers appear free of damage, carefully unpack the components and inspect them for damage. Also check the packing list and verify that all the items on the list are included.

Again, if any damage is found, report it to the carrier and to EdgeTech. If any items are missing, immediately contact EdgeTech. Do not install or operate any equipment that appears to be damaged.

Although the items shipped may vary, depending on the customer requirements, the 3300-HM system typically includes the following:



Topside Unit



Hull Mount Transducer Arrays



Connection Cable



AC power cords (2)



Software CDs



Manuals

After unpacking the system components, be sure to safely store the shipping containers, including any packing materials, for later use. When transporting or storing the system, all items should be packed in their original shipping containers in the same manner in which they were originally shipped, and always store the system in a dry environment when not in use.

4.2 Topside Installation

Once unpacked, the topside unit may be installed in a standard 19” rack. Several requirements are necessary for proper placement of the unit, and are addressed below:

4-2

3300 HULL MOUNT SUB-BOTTOM PROFILER

SECTION 3: INSTALLATION

4.2.1 Power Supply

The system power requirements are 120–220 VAC, 50/60 Hz. For the 3300 Topside Processor, the input voltage is auto sensing. For the Power Amplifier, you must select 120 VAC or 220 VAC operation manually.

4.2.2 Use of an Uninterruptable Power Supply

The AC power source should be continuously free of high-amplitude, high-frequency transients, as this type of interference could cause degraded performance or damage to the equipment. An uninterruptable power supply (UPS) with power surge protection is recommended for powering the equipment.

However, whether or not a UPS is used, the AC power source should never be the same as that being used to power electric motors, such as pumps and winches, on the survey vessel.

4.2.3 Selecting the Power Amplifier Input Power Voltage

To select the Power Amplifier input power voltage, first remove the amplifier from the rack. Then remove the top cover, locate the board at the lower right corner, and switch it to the required input power voltage as indicated by the arrow.

4.2.4 Changing to a Non-US Power Plug

An AC power cord is provided for connecting the Deck Unit to a standard U.S. 3-pronged outlet. For non-

U.S. power outlets you can modify this cord by cutting off the 3-pronged plug and attaching the appropriate plug. Refer to Table 3 1 for connection information.

4.2.5 Navigation Interface

The 3300-HM system accepts all standard National Marine Electronics Association (NEMA) 0183 message sentence formats from a connected global positioning system (GPS) or integrated navigation system.

4.2.6 Deck Unit Placement

The Deck Unit should be located and set up in a dry, sheltered area that is protected from weather and water spray. The placement area should also have a temperature that is consistently between 0°C and

40°C (32°F and 104°F). Avoid areas of direct sunlight, especially in tropical environments, as heat buildup could occur and viewing the LCD monitor and status indicators could prove difficult. The unit should be placed in on a surface that is flat and free from vibrational interference.

Secure the Deck Unit in place, using tie-downs if necessary, near the required AC power source. If you are mounting the 3300 Topside Processor and the Power Amplifier in a 19-inch rack other than the supplied rack mount enclosure, ensure that there is ample room behind the rack for connecting the cables. Support the components inside the rack using appropriate mounting brackets and secure the front panels using standard 19-inch rack front panel mounting hardware.

4.3 Hull Mount Array Installation

NOTE:

This section is a summarized version of the full installation guide, provided in EdgeTech document PN 0016695.

The transducer arrays for the 3300-HM system are mounted to the bottom of the survey vessel in a “Sea

Chest.” This chest is filled with fresh water in order to protect the array from corrosion, while providing a medium for the sub-bottom sonar signal to travel through.

A hatch on the top of the chest allows the deck crew to access the array in order to inspect or remove it between surveys. The bottom of the Sea Chest (facing the sea floor) is an “acoustic window,” which is made of a material that allows the signal to pass through it while still protecting the array.

Stainless steel trays are available from EdgeTech for mounting the transducers inside the user-provided

Sea Chest. However, the user may also construct the trays themselves by following the proper spacing

requirements listed below (for transducer array specifications, see sub-section

2.3

):



Install the transducer array must with the array parallel to the sea surface within a flooded steel enclosure.



For best results, use an acoustic window made of a material such as a high quality fiberglass with no air pockets (e.g., 'G10' glass board), 'Lexan', or a polycarbonate material. Construct the Sea

4-4 SECTION 3: INSTALLATION

Chest so that the acoustic window can be bolted to the sea chest using a bezel to secure it in place.



The steel enclosure is a steel box welded to a section of the hull that is flat and parallel to the sea surface. The sides of the enclosure should be high enough to allow inspection of the array; it is recommended that the sides of the box be at least 30 cm higher than the top of the transducers.

There should be a minimum of 5 cm between the sides of the transducers and the sides of the sea chest.



A sea chest for a 4 x 4 array (of KT-216 transducers) will have the following minimum inside dimensions:

Inside height 22 inches / 56 cm

Inside width 28.25 inches / 72 cm

Inside length 31.25 inches / 80 cm



Locate the steel box away from vibrating equipment and sufficiently deep below the water line to prevent air bubbles passing along the hull and under the array during high sea states.



Line all four vertical sides and the removable cover plate with a foam material such as ¼ inch (0.64 cm) (minimum) diver’s wetsuit neoprene. Attach it with a good neoprene cement (such as 3M

5200 moisture cured) to the sides and top of the sea chest.



Bolt the transducer array to an angle bracket that is welded to the inside of the box so that the faces of the transducers are within 2 cm of the hull plate, but not touching it. The array is installed in the box one row (rack) of transducers at a time.



The steel box should have a removable cover to allow installation and removal of the transducer array. The cover should bolt to the top of the box and have a gasket to prevent leakage. The cover

Plate should have a fill pipe to fill the Sea Chest with fluid and a bleeder valve to exit the air from the Sea Chest. The Sea Chest must be free of any air pockets or bubbles for the transducers to operate properly.



Fill the tank with fresh water (preferably distilled) from the ship’s fresh water supply. If the system will be operated at temperatures near or below the freezing point for fresh water, antifreeze may be added so that the freezing point is below that of sea water (Propylene Glycol antifreeze is acceptable).



Drain the tank and pipes when the ship is in dry dock if there is a risk of freezing weather. Vent all air from the pipes and tank after filling and before operating the sonar to prevent signal degradation.


4-5



Install a stuffing tube and gland nut to allow a 0.8 cm diameter electrical cable to pass through the tank. This cable connects the transducer array to a water-resistant interface box that is mounted to a bulkhead within 3 meters of the tank. The interface box contains a pre-amp, matching transformer, and T/R switch. The interface box enclosure is plastic and approximately

18 cm high by 18 cm wide by 12 cm deep. A standard 50-meter 3300-HM deck cable connects the interface box to the 3300-HM topside processor.

4.4 Connecting the System

WARNING!

Do not attach any cables or wires while the system is connected to the ship's power, as severe electrical shock may occur.

Once the transducer arrays have been mounted, the Sea Chest has been filled and vented of air, and the topside unit has been unpacked and secured, the user may proceed with connecting the 3300-HM system components in preparation for use:

1. Ensure the AC voltage selection switch in the amplifier is set to the proper voltage.

2. Connect the deck cable to the Hull Mount.

3. Connect the underwater cable to the Amphenol connector at the back of the amplifier unit.

4. Connect the video monitor.

5. Connect the keyboard and trackball to the front panel of the system.

6. Connect a thermal printer (optional)!

CAUTION!

Always connect the T/R box end connector before connecting the cable to the deck unit to prevent connecting an energized connector. This may cause damage to components in the T/R box.

5-1

SECTION 5:

OPERATI ON

The purpose of this section is to provide general information on the interface between the 3300 Hull

Mount transducers and the 3300-HM topside unit. The interface between the 3300-HM and the DISCOVER

Sub-Bottom software can be found in the DISCOVER Sub-Bottom Software Manual

5.1 Activating the System

1. Turn on the POWER SUPPLY switch on the back of the Deck Unit. This switch can be left in the on position at all times if desired.

2. Turn on the POWER switch on the Power Amplifier.

3. Turn on the SYSTEM POWER switch on the 3300 Topside Processor.

4. The SYSTEM indicator on the 3300 Topside Processor should illuminate and remain on, and the

HARD DISK indicator should flash for two to three minutes while a self test is run. After this test is completed, the HARD DISK indicator will flash periodically.

5. Turn on the LCD monitor.

5.2 File Format

Data is archived to the hard drive of the system in two formats, EdgeTech’s native format JSF and the SEG-

Y format. The SEG-Y recording can be turned on or off in the software but the EdgeTech Format is always recorded. This is because the JSF format stores a much greater amount of information than the standard

SEG-Y.

5.2.1 EdgeTech’s Native JSF Format

Please refer to EdgeTech JSF File Format Manual (document 0004824) for more detailed information.

5.2.2 Standard SEG-Y Format

In the standard SEG-Y format, all sonar data in traces is represented via IEEE 32-Bit floating point numbers

(as per the standard). All fields are byte oriented as per the standard (Big Endian). That is, for a 32-bit integer, the 8 MSBs are in the first byte. The EBCDIC header is really in EBCDIC (or ASCII).

For Intel based processors, all of the above are not standard and will require conversions. For example, the sonar data must be converted from IBM to IEEE floating point. Integers must be converted from Big

Endian to Little Endian, and the EBCDIC header must be converted to ascii. ONLY envelope data is saved

(one float per sample).

5-2 SECTION 4: OPERATION

5.2.3 Palette File Format

Each display channel can have a color palette, which is specified by a .jsp file. These files are text files with numbers separated by white space. The numbers must be ordered in groups of 4. For each group the values are:



Index (0 to 255)



Red Intensity (0 to 255)



Green Intensity (0 to 255)



Blue Intensity (0 to 255)

The indices must be increasing in value. If there are gaps in the index then intermediate color values will be interpolated. Here is an example table for a linear gray step wedge type palette:

0 0 0 0

255 255 255 255

5.3 Triggering and Coupling

To avoid interference, the 3300-HM system supports the following different type of triggering Modes:

Internal Trigger:

Coupled Mode:

External Trigger:

In this mode the user may specify the ping rate in Hertz (e.g. 3Hz) or ping range

(in Meters). The system will use the closest available inter-ping interval (e.g.

332.99ms), and repeatedly re-trigger the system at the expiration of this period.

This mode applies only to a combined sub-bottom and side scan system. In coupled mode the applicable subsystem is triggered when the master subsystem triggers. The trigger timing for coupled systems takes account of differing transmit pulse lengths and minimizes inter channel interference.

In this mode the system is triggered by the external event received via the Trigger

IN BNC connector in the back of the system. When the hardware trigger is asserted (active log) a new ping occurs.

Note that there is a minimum trigger interval (maximum rate) of each subsystem which is dependent on the Pulse Type used, and is proportional to the pulse length. That is, a longer pulse will also set a longer minimum interval, to keep the ON/OFF duty cycle of the Power Amplifier below the maximum allowed, typically 1:10. The actual trigger interval used will be the LARGER of the user interval and the Power

Amplifier imposed limit.


6-1

SECTION 6:

MAINTENANCE

The EdgeTech 3300-HM system is ruggedly designed and built from reliable, long lasting components to reduce maintenance to a minimum. To insure proper and continuing service of the system some periodic maintenance is recommended.

6.1 Hard Drive Disk

The system contains a standard SATA hard drive for storing programs and configuration information. An

image of the hard drive is provided on a thumb drive disk. See

APPENDIX A: SYSTEM RESTORE

for more

information.

6.2 Array Connectors

To extend the life and increase the reliability of the connectors, apply a thin film of silicone dielectric grease to the entire surface of each male pin. Grease should also be applied at the entrance of each socket.

Re-lubrication is recommended every three to five mating cycles. The use of Novagard G624 silicone compound or equivalent is recommended for lubrication.

Inspection should be performed regularly to check for corrosion on the contacts. Oxidation may be removed from the male contacts by using no less than #800 wet/dry emery paper cut in strips equal to or less than the width of the contact and rubbing lightly. A pencil eraser can be used instead. Female sockets may be cleaned using a cotton swab and rubbing alcohol. A .22 caliber bore brush with only nylon bristles may be used to remove light oxidation.

Connections inside the hull mount chest only need to be checked once every year.

Remember to always install the dummy connectors on the sea cable and the pigtail when not in use.

TROUBLESHOOTING

The following tests and solutions are meant to assist with basic troubleshooting. Contact

EdgeTech

Customer Service

if these fixes fail to address the problems with your system.

7.1 Freq. Plots and Raw Data Time Series Analysis Using J-STAR

The ability of the J-STAR program to request and display raw data (directly from the ADC converter) is invaluable in diagnosing many potential failure modes. Raw data (as opposed to processed and chirped data) allows direct interpretation (via scope like display). This helps to determine noise levels, and the proper operation of, transmit power electronics. The J-STAR program also assists interpretation with FFT analysis that show interfering noise sources by frequency distribution and spectral amplitude.

The J-STAR program may also be used to acquire raw data, and log this data to disk for offline analysis.

Having recorded raw data available for analysis by EdgeTech engineers will often speed up the resolution of suspected problems. Such files may be sent to EdgeTech in CD-ROM format or if small as email attachments. Many system control and setup parameters are recorded in these raw data files which will assist in problem diagnosis.

The Graph tab on the Control Panel will display any channel of data and its FFT (frequency spectrum).

1. Start J-STAR

2. Turn pinging on

3. Go to the Graph Tab in the Control Panel

4. You should now see something like the following figure:

If checked the displays are re-scaled for EACH redraw / data update, so that the min / max amplitudes of the current data span the available display range. This can be confusing to the eye if the amplitudes of the signals vary greatly from ping to ping, as each display will appear to have the same amplitude unless the axes values are carefully observed. It is

SAFEST to leave this unchecked, and manually ReScale as required.

NOTE:

ONLY the data being displayed is saved, i.e. channel 3 in this case.

No other channels are saved.

7-4 SECTION 7: TROUBLESHOOTING

Signal Level Cursor: These 2 yellow lines can be dragged vertically to mark and display amplitude levels. For raw data, the amplitudes are in A/D counts. The ADC values are represented in 16 bits, which allows for 65536 discrete levels.

These are interpreted as bipolar signals with an amplitude range of +/-

32767.

Raw Data Display: All the raw data acquired by the A/D subsystem is displayed in the top window. The A/D capture sequence begins immediately prior to the start of the Transmit pulse for the channel (τ = 0). The entire transmit pulse

(which is unavoidably coupled into the receive channel) is visible in the early part of the display.

Following the transmit pulse (τ = 8.3msecs in this case) the lower amplitude received echo data is visible.

The A/D converter is overloaded during the Transmit pulse by the extremely large amplitude signals injected into the receiver. For this reason, the signal may appear to collapse slightly during the Transmit pulse, but the display should show +32767 and –32767 amplitudes during the Transmit interval. See the figure below for raw data display where the Transmit power for the channel is set to zero.

In this case transmit power for the side scan channel has been set to zero in the SSL control tab. The Power

Amplifier turn on and turn off transients, are still visible in the time record and indicate that the power to the amplifiers is good, and that the power amplifier on/off control is working correctly. The absence of transmit energy would indicate a failure in the transmit signal generator, if the power were not intentionally set to zero.

7.2 System Does Not Operate

This section will guide you through a series of symptoms and actions that you should follow if the sonar is not operating at all. Go to the second section if performance or image quality is poor. Before continuing with this section, please check that the following setup and connections have been completed:

7.4 Frequently Asked Questions

1. What are the 3300-HM data cable requirements?

Three shielded twisted pairs. One set is used for the transmitter and is 18-gauge wire. Two sets are used for receiving and are 20 gauge. The receiver set is used for 12 VDC, pre-amp power, common, signal, and spare.

2. Can you interface DISCOVER Sub-Bottom to a transmit/receive hull mounted array that is customer

supplied?

This can be done, but the following special engineering and calibration must be accomplished so that you will get the very best results from the interface.

The output impedance of the DISCOVER Sub-Bottom power amplifier needs to match the input impedance of the transmitting array. This will maximize power transmission; otherwise, power is wasted/lost in the amplifier without getting to the transmitters. The transformer has to be supplied with the correct turns ratio. A hydrophone needs to be placed below the transmitters temporarily so that the system can be calibrated. Based on the calibration, the system needs to be tuned in order to flatten the spectrum to improve the resolution of the records. EdgeTech provides engineering services to do this.

3. How does the system interface to a navigation device?

The 3300-HM system interfaces to Navigation inputs via one of the available RS-232 communication ports.

4. How do the environmental conditions affect the performance of the system?

Geological Conditions The 3300-HM operating parameters and specifications are greatly affected by the geologic conditions that the acoustic energy transmitted from the 3300-HM encounters. A very dense geologic interface such as rock, coral, sand, stone, shell beds, etc, will limit the penetration into the sub-bottom. This is caused by the density interface reflecting most, if not, all normal incidence acoustic energy back to the transmitter / receiver resulting in little penetration.

Air / Water Interface The air / water interface reflects 99.8 percent of all acoustic energy it receives. It therefore is evident that when air or gas is encountered in the water column or sub-bottom geology the acoustic energy transmitted by the array of transducers will be reflected back to the transducers resulting in little or no penetration into the seabed.

Ship's Wake

The ship's wake is a very turbulent area just behind the ship. When operating an acoustic device in or near the wake the transmitted acoustic energy encounters highly charged aerated water caused by the cavitation of the ship's screws. If the 3300 Hull Mount is operated in this area, the


Noise

Ship's Motion

7-9

acoustic from the aerated water is reflected back to its source, as in the case discussed in the preceding paragraph.

The 3300-HM is designed to operate in a horizontal position relative to the sea floor. The turbulence encountered when operated in or near the ships wake will cause instability in the 3300-HM reducing the effectiveness of the output energy in penetrating the sub-bottom sediments.

Operating other acoustic instruments with frequencies within the system bandwidth simultaneously with the 3300-HM system can result in data distortion.

The 3300-HM is designed to work in a relatively stable horizontal plane.

Excessive ship motion can cause instability in the reception of sound waves resulting in reduced performance. Rough sea conditions, sharp turns of the ship and any similar external induced motions will have a similar effect on the system operation. However, this can be improved by

DISCOVER Sub-Bottom’s Heave Compensator (see respective software manual for more information).

Connect any industry-standard NMEA 0183 GPS to the Navigation COM port on the EdgeTech Processor

(Com 1 is default). Most GPS receivers made in the past 5+ years output the NMEA 0183 (version 1.5,

2.0/2.1, or 2.3) data language. GPS receivers can be connected by a serial cable (provided by the GPS manufacturers) to the EdgeTech topside through a standard 9- pin serial port. Refer to sub-section B.5

Serial Port Connections for the pin out of the 9 pin serial connector.

The following information describes the serial port interface parameters for acquiring navigation strings from a connected GPS unit or integrated navigation computer to the DISCOVER processor serial port. The system will also accept Annotation and Event mark strings in accordance.

Several of the messages conform to the NMEA 0183 protocol. For additional information refer to:

B.3 Port Selection

The port assigned to receive the navigation messages is assigned in a supporting file for the DISCOVER application or any other user named *.jni file. This is a simple text file with many system settings and parameters, to set the assigned port, edit the file and make the changes as below:

The section and syntax for the serial port assignment and configuration is:

[Nav0]

Baud=4800

Port=1

Enable=1

The file is large so it is easiest to search for the Keyword [Nav0] to find this section.

The baud rate and port number to use are set here. Valid Baud rates are 4800 to 19200 depending on your NMEA source.


B-3

The DISCOVER software will support up to 3 serial ports for connecting to any sources of these serial data strings. The messages may come in on any enabled port, or they may all be input via one port. No distinction or priority is given to any port over another. It is safest to only enable those ports you need that are supplying valid data.

The format for the remaining ports is as above with the keywords, [Nav1, Nav2].

Table B-9: 9 Male Pin Out

The following outlines the different pins from the comport connection that EdgeTech processor uses for communication

Pin # 2: (usually brown) is Receive (which would connect to the transmit pin on the GPS). This connection will take the position data from the GPS for use in the DISCOVER software. This is a necessary connection for GPS communications

Pin # 5: (usually green) is Ground. This can be connected to the common ground from the GPS wiring. This is a necessary connection for GPS communications

Pin # 3: (usually red) is Transmit. This connection will go back to the GPS. Pin # 3 is not a necessary connection for using DISCOVER software for Real-Time positioning. Only proper connections to pins number 2 and 5 are needed for to log navigation data.

B.6 Troubleshooting

Problem: When connected to a GPS, the computer’s mouse acts erratically and seems to be 'jumping' around

Solution: A Windows bug discovered by Microsoft where Windows detects a connected GPS as a mouse-

-this produces a jumping cursor problem. The following are the directions supplied by Microsoft support to correct the problem:

1. Turn off the GPS and close DISCOVER Software.


B-11

2. Right-click on the My Computer icon and select Properties.

3. Select the Hardware tab, and click the Device Manager button.

4. Next to "Mice and other pointing devices," click the plus button to expand this list. You should see at least two items listed. One is the mouse you normally use, and the other will probably be listed as "Microsoft Serial Ball Point."

5. Highlight "Microsoft Serial Ball Point" and click the Disable button at the top of the window (it is usually the second button from the right; hover the cursor over it and read the Tool Tip to verify).

6. In the confirmation message window that appears, click Yes.

7. Close the Device Manager.

8. Plug in/turn on your GPS.

9. Restart DISCOVER Software.

Problem: No communications between GPS and DISCOVER Software

Solution: When DISCOVER isn't getting the GPS data during data acquisition, it's a good idea to check outside of DISCOVER to be sure the serial port is receiving the data. If the ports do not see any GPS data coming in, then DISCOVER will not be able to see the signal. HyperTerminal, one of the programs which come with Windows, is a useful troubleshooting utility, since it reads any information being received by the system through any available COM port. Here are the steps:

NOTE:

DISCOVER and all other programs, especially any that use COM ports for other connections, should be closed while running the

HyperTerminal program. The GPS should be set to its NMEA mode in its

Interface Setup area for this test. The GPS should be set to its Simulator mode if indoors or having difficulty obtaining the GPS Sat. fix.

1. Click Start, then Programs, then Accessories, then Communications, then HyperTerminal

2. In the window that opens titled HyperTerminal, double-click on the icon which says "Hyperterm", the one with the monitor sitting next to a phone.

3. If a window comes up asking if you want to configure a modem now, select "No" or "Cancel".

Otherwise, proceed to the next step.

4. Another window titled "Connection Description" appears. In the Name: box, type in the letter t for "test". Click on OK.

5. Another window pops up with the title "Phone Number". The only field of interest here is Connect

Using:, which must be set to "Connect to COM1". Click on OK.


6. The window "COM1 Properties" appears. The only field to change here is Bits per second:, which should be set to "4800", since the NMEA 0183 standard specifies 4800 baud rate. Click on OK.

7. The main white HyperTerminal window becomes completely visible, hopefully with GPS data scrolling upward. Every sentence must begin with a dollar sign and five letters. If the screen is blank, this means no data is coming in through the port.

8. When finished viewing the screen, select "Exit" from the File menu. When asked if you want to disconnect now, click on Yes. When asked if you want to save session, click on No.

Repeat the above steps for other COMs, replacing COM1 with COM2, COM3 and COM4. If none of these will reveal GPS input, then the problem lies in the physical serial port, the GPS receiver, or the connection between the two.

At this point, one of three things can happen:

1. An error message appears:

This means that the COM port selected is not available or functioning properly. Close

HyperTerminal and repeat the process, trying a different COM port. If you are certain that you are

selecting the proper COM port, contact


for further troubleshooting

tips.

2. The screen goes blank screen with a flashing cursor.

The chosen COM port is not currently receiving NMEA data. Close HyperTerminal and repeat the process, trying a different COM port. If you are certain that you are selecting the proper COM port, check the output settings on the GPS. If you are certain that the GPS is outputting NMEA strings, use a Null Modem to swap pin 2 and 3 (TX & RX).

3. A screen with text scrolling upward appears.

The GPS unit is successfully connected. Good GPS data will look like the following:

$GPRMC,201502,A,4251.2939,N,07054.4254,W,000.0,000.0,291002,016.3,W*7C

$GPGGA,201502,4251.2939,N,07054.4254,W,1,07,1.7,55.6,M,-32.7,M,,*4A

$GPGLL,2600.0100,N,800000.0000,W,151228.99,A*67

$GPVTG,315.65,T,314.15,M,3.8,N,7.0,K*48

$GPZDA,151229.25,28.08,1997,06,00*45

The data you see scrolling by indicates current position (among other things). Note the COM port used and exit HyperTerminal. When asked if you want to disconnect now, click on Yes. When asked if you want to save session "Test", click OK.
