10 25 kW radar system overview

The radar system is intended for use in a marine environment.

The 25 kW radar system consists of a scanner and an open array, connected to the 25 kW radar processor by a prefabricated interconnection cable which is available in two lengths (NS003105 or NS003106).

where A is the radar processor, B is the vessel's power supply (24 V DC ONLY), and C is the Network Linker (NS004721).

The 25 kW interconnection cable contains separate motor power wires, and there is a separate motor power fuse in the radar processor.

If the radar processor is connected to a Northstar 6000i or 6100i, it communicates with the display unit through the 6000i and 6100i radar communications cable (NS003107). An optional extension cable (NS003108) is available.

If the radar processor is connected to a Northstar 8000i system, it communicates with the 8000i Network Linker (NS004721) through the 8000i network cable (NS00481X).

DC power for the scanner and radar processor is provided through a power cable that connects the radar processor to the vessel's DC power supply. The power cable is not supplied.

Northstar 25 kW Radar Installation Manual

11 Install the radar

A radar unit should only be installed by a qualified marine technician, as potentially lethal high voltage is present along with heavy rotating parts. 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 6000i or 6100i system or 8000i system to work with the radar

 adjusting the radar for proper performance.

Don't take any shortcuts, and follow these instructions carefully.

NOTE: For the radar overlay to function properly on the chart screen, you must correctly install and calibrate a separate heading sensor. Without the heading sensor, you cannot overlay the chart. A 10 Hz heading output rate is required for best radar/chart overlay performance.

This section explains how to:

 choose the correct location for the scanner

 install the scanner on a power boat or a yacht

 choose the correct location for the radar processor

 install the radar processor

Read the important warning and safety information in the Preface before you install the radar.

11.1 Choose the scanner location

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 aren't any obstacles.

The higher the installation position, the longer the radar ranging distance, but the minimum range that the radar can detect targets increases the higher that the radar is mounted.

Also see the sections on installing the scanner on a power boat or yacht.

When you're deciding on the location, consider the following:

 the length of the interconnection cable supplied with your radar is usually sufficient. If you

think you'll need a longer cable, consult your Northstar dealer before installation, because a longer cable may reduce the performance of the radar.

 if the roof of the wheelhouse is the highest existing location, consider installing a radar mast

or a pedestal on which you can mount the scanner. You may also need to construct a working platform for your own safety during installation and servicing work.

 if you mount the scanner on a pedestal or base, ensure that rain and sea spray can drain

away from it rapidly.

 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.

 the scanner is usually installed parallel to line of the keel

 ensure that the location site provides the scanner with a clear view of the front of the vessel.

Northstar 25 kW Radar Installation Manual

DON'T DO THIS!

 DON'T install the scanner too high up, where its weight will alter the stability of the vessel

and cause degradation of the radar picture over short ranges (see "How to find the optimum height for the scanner").

 DON'T install the scanner close to lamps or exhaust outlets. The heat emissions may cause

the equipment to breakdown and soot and smoke will degrade the performance of the radar.

 DON'T install the scanner close to the antennas of other equipment such as direction

finders, VHF antennas, GPS equipment and so on, because it may cause interference.

 DON'T install the scanner where a large obstruction (such as an exhaust stack) is at the same

level as the beam, because the obstruction is likely to generate false echoes and/or shadow zones.

 DON'T install the scanner where it will be subjected to strong vibrations (such as a derrick

post) because these vibrations will degrade the performance of the radar.

 DON'T install an open array close to halyards or flags because the wind could wrap these

around the scanner and jam it.

DON'T 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:

2 kW radar STD 2.3 ft (0.7 m)

STEER 1.6 ft (0.5 m)

4 kW radar STD 6.5 ft (2.0 m)

STEER 5 ft (1.5 m)

6 kW radar STD 7.5 ft (2.3 m)

STEER 5.7 ft (1.75 m)

10 kW radar STD 7.9 ft (2.4 m)

STEER 6 ft (1.8 m)

25 kW radar STD 7.9 ft (2.4 m)

STEER 6 ft (1.8 m)

Northstar 25 kW Radar Installation Manual

11.1.1 Power boat installations

Normally, you should install the scanner horizontally, to produce an equal sweep around the power boat:

However, when the power boat is traveling at high speed, the bow rises up out of the water and if the elevation angle (trim) of the bow is raised up so that it equals, or exceeds, 50% of the vertical beam width of the radar, this can cause two problems:

 ahead of the power boat, the beam is projected too high to sweep the water surface

effectively. Targets can be missed completely or appear at a very poor resolution on the display screen.

 astern of the power boat, the beam is projected too low and is concentrated over a small

area of water so that sea clutter becomes a problem on the display screen.

In this case, you're recommended to install the scanner so that is tilted down at the front, at an angle that will produce an almost horizontal sweep when the power boat is running at speed.
