Introduction
This manual explains how to install the Halo® Pulse Compression Radar system. This manual
should be used in conjunction with the installation manual provided with the display.
This manual is written for professional marine technicians, installation technicians, and service
technicians. Dealers may use information contained in this document.
The Halo® Pulse Compression Radar combines the best characteristics of traditional pulse and
FMCW broadband radar systems, our Halo™ Radar uses Pulse Compression technology to
provide an unprecedented mix of long and short detection range, high target definition, and
minimal clutter. Solid State technology means minimal warm-up time and maximum oceangoing reliability, while compliance with upcoming Low Emission standards makes Halo Radar

The radar system consists of a pedestal, antenna, RI-12 radar interface and connection cables.
An Ethernet network cable is used to connect the RI-12 radar interface module to the navigation
Ethernet network and is intended for use in a marine environment.
¼¼ Note: Antennas are available in three sizes 3 ft, 4 ft and 6 ft to suit customer requirements.
¼¼ Note: At the time of release the Halo radar will only work with Simrad NSSevo2 and NSOevo2
systems
¼¼ Note: The radar should be installed by a qualified radar technician.
Warnings
! Warning: Use the radar at your own risk. Your radar is designed as a navigation aid.
Always compare the navigation information received from your radar with data from other
navigation aids and sources. When a conflict arises between the navigation data from
your radar and data from other navigation aids, make sure you resolve the conflict before
proceeding with navigation.
A CAREFUL NAVIGATOR NEVER RELIES ON ONLY ONE METHOD TO OBTAIN NAVIGATION
INFORMATION.
International Regulations for Preventing Collisions at Sea mandate that when radar is on
a vessel, the radar must be used at all times, regardless of weather conditions or visibility.
Numerous court decisions have ruled that the radar must be used, and the radar operator
must know all operational aspects of radar performance. Otherwise they will face a greater
risk of liability if an accident occurs.
! Warning: High Current, Stored and Microwave Energy Hazard. Technicians must
exercise extreme care when working inside the unit. ALWAYS remove power before removing
the cover. Some capacitors may take several minutes to discharge, even after switching off
the radar. Before touching any high voltage components, ground them with a clip lead.
! Warning: Halo™ Pulse Compression Radar’s blue 4 level static accent pedestal lighting
may not be approved for use in your boating location. Please check your local boating
regulations before turning the blue accent lights ON.
! Warning: The microwave energy radiated by a radar antenna is harmful to humans,
especially to the eyes. NEVER look directly into an open waveguide or into the path of
radiation from an enclosed antenna. Remove power or use the Safety switch on the rear
of the Pedestal to turn off the radar whenever it is necessary to work on the antenna unit or
other equipment in the beam of the radar.

! Warning: Before commencing any installation or maintenance on the Halo radar make
sure the safety switch on the rear of the pedestal is set to OFF
There is a transmit interlock that prevents radar transmissions if the scanner is not rotating.
However, a high voltage remains for a period of time after the system is turned off. If you are
not familiar with this type of electronics, consult with a trained service or installation technician
before attempting to service any part of the equipment.
Installation includes:
mechanical mounting
electrical wiring
configuring the display or network system to work with the radar
adjusting the radar for proper performance
The radar’s ability to detect targets depends greatly on the position of its scanner. The ideal
location for the scanner is high above the vessel’s keel line where there are no obstacles.
A higher installation position increases the radar ranging distance, but it also increases the
minimum range around the vessel where targets cannot be detected and increases seaclutter
pick up
When you’re deciding on the location, please consider:
The length of the 20 m (66 ft) interconnection cable supplied with the radar is usually sufficient.
A longer 30 m (98 ft) cable is available. 30 m (98 ft) is the longest the cable that can be used.
If the roof of the wheelhouse is the highest existing location, consider installing a radar mast or
tower on which you can mount the radar. You may also need to construct a working platform
for your own safety during installation and servicing work.
If you locate the scanner on the mast, position it on the forward side so that there is a clear view
to the front of the vessel.
It is preferable to install the scanner parallel to the line of the keel.
DO NOT DO THIS!
DO NOT install the scanner too high up, where its weight will alter the stability of the vessel and
cause degrade the radar picture over short ranges.
DO NOT install the scanner close to lamps or exhaust outlets. The heat emissions may cause the
equipment to break down. Soot and smoke will degrade the performance of the radar.
DO NOT install the scanner close to the antennas of other equipment such as direction finders,
VHF antennas, GPS equipment etc, as it may cause interference.
DO NOT install the scanner where a large obstruction (such as an exhaust stack) is at the same
level as the beam. The obstruction is likely to generate false echoes and/or shadow zones. If
no other alternative location use the sector blanking feature in the radar software. (see “” on
page 33)
DO NOT install the scanner where it will be subjected to strong vibrations because the
vibrations could degrade the performance of the radar.
DO NOT install an open array close to halyards or flags because the wind could wrap these
around the antenna and jam it.
Installation Guidelines |Halo pulse compression radar installation manual
Compass safe distance
! Warning: Do not install the scanner inside of the recommended compass safe distances
of any navigation instruments such as the magnetic compass and the chronometer. The
compass safe distances are as follows:
Minimum distance to install near the ships compass is 1.0m (3.3 ft).

Considerations for direct roof mounting
When deciding a suitable mounting location for the Halo® Pulse Compression Radar be aware
that the vertical radar beam extends to 25° either side of horizontal. With 50% of the power
projecting in a beam 12.5° off horizontal. If the radar beams cannot clear the roof line, this will
decrease performance of the radar. Depending on the size of the hard top of the vessel, it is
recommended to elevate the antenna to allow the radar beams to clear the roof line. Below are
guide lines on heights above the hard top.
The below illustrates an installation with the Halo® Pulse Compression Radar mounted directly
on to a large hard top. This installation could suffer decreased performance as the radar energy
is either reflected or absorbed by the hard top.
¼¼ Note: Where the mounting surface is constructed of any form of metal you must elevate the
dome so that the beam has complete clearance, else performance will be severely impaired.

Hardware mounting
Install the RI-12 radar Interface module
Install the RI-12 in a dry location away from spray, rain, drips and condensation or excessive
heat. The mounting position should be easily accessible.
Always mount the RI-12 vertically, with the cable entry points facing downwards. This is to assist
in cooling and to assist stopping any possible water ingress though the cable grommets.
The RI-12 must be located where it can be easily connected to the ship’s ground, the pedestal
interconnection cable, the power cable and the NMEA 2000 network. Check that these cables
and the ship’s ground can easily reach the radar processor BEFORE you drill.
Use fasteners suited to the mounting surface material. If the material is too thin for self tappers,
reinforce it, or mount the RI-12 with machine screws nuts and washers. Use only 304 or 316
stainless steel fasteners. Mark the screw locations using RI-12 box as a template, and drill pilot
holes.

Pedestal Interconnection cable
The interconnection cable connects the radar pedestal to the RI-12 Interface module. The cable
connects to the pedestal using a 14 pin connector. The pedestal 14 pin connector can be set
to either rear exit or discrete exit underneath the pedestal. (see “Pole or tower mount: Discreet
cable connection” on page 19)
¼¼ Note: Protect the connectors especially the RJ45 connector when pulling cable through the
boat and avoid putting strain on to the connectors.
The interconnection cable is 9 mm in diameter. A 14 mm hole will be required in order for the
RJ45 (Interface module end) to pass through bulkheads or 24 mm hole for the 14 pin connector
(pedestal end) to pass though.
Run the interconnection cable between the pedestal and the location of the RI-12 Interface
module.

Remote power control
Remote power control is a feature that allows the power state of the radar to be controlled
either from a switch or when a compatible multifunction display is powered on or off.
¼¼ Note: The power control jumper must be moved from AUTO to REMOTE for the radar to use
the remote power on function.
¼¼ Note: +V DC (5 V DC - 32 V DC) from either a multifunction display set as power control master or a switch can be applied to the REMOTE port of the AUX IN connector for the remote
power on to function.
Connect the yellow wire to external wake up of a compatible multifunction display to the
remote input. The radar will turn on when the display is turned on. The display must be set to
‘Master’ under Power Control. (Please refer to the displays user manual)
¼¼ Note: If the radar is turned off via remote power control while transmitting, The radar will auto
park the antenna before shutting down.
¼¼ Note: There must be a common batt -ve for all devices on power control bus.

NMEA 2000
The RI-12 can be connected to a Micro-C NMEA 2000 network to receive heading and position
information.
A heading sensor is required for the following functionality;
• MARPA : heading at 10 Hz or faster is required for the radar to calculate MARPA tracking. Heading
must also be connected to the display.
• Radar Chart overlay and North-up: Heading is required by the multi-function display
For heading sensors that output NMEA 0183 (see “NMEA 0183” on page 30)
For magnetic heading sensors, heading calibration should be performed before using MARPA
or Chart Overlay, and repeated annually, and after any major structural changes to the vessel.

NMEA 0183
The RI-12 has one NMEA 0183 (RS422) to accept heading and position information. The NMEA
0183 port is auto sensing and can accept 4800, 9600, 19200 or 38400 baud rates.
Sentences used HDG, HDT, HDM, GGA, GLL, RMC, VTG. Heading should be at a minium of 10
Hz update rate.
NMEA 0183 RX_A
NMEA 0183 RX_B
RI-12 heading source selection:
The RI-12 receives heading via the NMEA 2000 network and transmits this data to the radar,
where MARPA processing is performed.
For Simrad installations with more than one heading source the RI-12 will use the Simrad group
source. The source used by the Simrad group can be viewed or changed via the multifunction
display in the Settings>Network>Sources… menu.
¼¼ Note: If an NMEA 0183 heading source is connected the RI-12 will use this. It will ignore a
NMEA 2000 heading source.
Antenna park
The Halo® Pulse Compression Radar has the ability to stop rotating the antenna and hold it at
a predetermined angle in relation to the ships heading line. The park angle is set in the display
(see “Adjust open array park angle” on page 34). In conjunction with this setting there is a
park angle retention feature which is a very low current electromagnetic brake that will provide
resistance for the antenna to maintain a parked angle against wind and movement. The park
brake requires a continuous low current DC supply (10-32 V DC). This draws less than 100uA.

Setup and configuration
Setup and configuration of the Halo® radar has been simplified compared to traditional pulse
radars. There is no zero range adjustment (time delay), no warm up time, and no burn in
required.
Source
On the radar page, choose the radar to be setup using the source drop down. MENU>SOURCE
When setting up the Halo Pulse Compression radar choose either Halo-A or Halo-B
¼¼ Note: Following settings require the radar to be in Transmit mode. MENU>TRANSMIT
Entering radar setup on your display
Enter radar installation by pressing MENU > SETTINGS > RADAR > INSTALLATION.
There are three essential steps to setup the Halo® radar:
• Set antenna length
• Set antenna height
• Set bearing alignment
Select the antenna length
Select the correct length of antenna. Select Save to exit back to the radar installation page.
Adjust antenna height...
Set the radar scanner height. Use the slider control or the “+” or “-” buttons to set the value then
SAVE.
¼¼ Note: The antenna height is the height of the antenna above the water line. It is very important to set the antenna height configured correctly as this will affect the sea clutter function.
Do not set the height to 0.
32 |
Setup and configuration |Halo pulse compression radar installation manual
Adjust bearing alignment...
Adjust the heading marker. This is to align with the heading marker on the screen with the
center line of the vessel, this will compensate for any slight misalignment of the pedestal during
installation. Any inaccuracy will be evident when using MARPA or chart overlay.
Point the boat towards a stationary isolated object. Adjust the bearing alignment so the
heading line touches the end of the same object.
Use the slider control or the “+” or “-” buttons to set the value then SAVE
Setup and configuration | Halo pulse compression radar installation manual

Sector blanking
On vessels where the radar is installed in close proximity to a mast or structure that could cause
unwanted reflections or interference to appear on the radar image. Use the sector blanking
feature to stop the radar from transmitting in the direction up to four sectors.
¼¼ Note: Sectors are setup relative to the heading line of the radar. The bearing of the sector is
measured from the front of the vessel to the center line of the sector.
Adjust open array park angle
The park angle is the final resting position of the antenna relative to the heading line of the
radar when the radar is set to standby. The antenna will stop rotating at the desired offset.
Optionally the antenna can be held in place against wind by connecting the antenna park wire
(see “Antenna park” on page 30).
¼¼ Note: When entering standby the antenna may rotate multiple times before coming to rest
Fwd.

Sidelobe suppression...
¼¼ Note: This control should only be adjusted by experienced radar users. Target loss in harbour
environments may occur if this control is not adjusted correctly.
Occasionally false target returns can occur adjacent to strong target returns such as large ships
or container ports.
This occurs because not all of the transmitted radar energy can be focused into a single beam
by the radar antenna, a small amount energy is transmitted in other directions.
This energy is referred to as sidelobe energy and occurs in all radar systems.
The returns caused by sidelobes tend to appear as arcs:
When the radar is mounted where there are metallic objects near the radar, sidelobe energy
increases because the beam focus is degraded. The increased sidelobe returns can be eliminated
using the Sidelobe Suppression control in the Radar installation menu.
By default this control is set to Auto, and normally should not need to be adjusted. However
if there is significant metallic clutter around the radar, sidelobe suppression may need to be
increased. The control should be adjusted as follows:
34 |
Setup and configuration |Halo pulse compression radar installation manual
1. Set radar range to between 1/2 nm to 1 nm and Sidelobe Suppression to Auto
2. Take the vessel to a location where sidelobe returns are likely to be seen. Typically this would be
near a large ship, container port, or metal bridge
3. Traverse the area until the strongest sidelobe returns are seen
4. Change Auto sidelobe suppression to OFF then select and adjust the sidelobe suppression
control until the sidelobe returns are just eliminated. You may need to monitor 5-10 radar
sweeps to be sure they have been eliminated
5. Traverse the area again and readjust if sidelobes returns still occur
6. Exit the installation menu
