  • Page 13: 25 Kw Radar System Overview

    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).

  • Page 14: Install The Radar

    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.

  • Page 16: Power Boat Installations

    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...

  • Page 18: How To Find The Maximum Detection Range

    An example of an A-B Line is shown in the picture. If you install the scanner below the A-B line, the scanner will be too low. It will be difficult to acquire distant targets and the superstructure will be more likely to impede the passage of the beam and generate false echoes. If the scanner is installed too high above the A-B line, the beam will miss close targets and increase sea clutter return.

  • Page 19: How To Reduce False Echoes And Shadow Zones

    Calculations using the formula show that, at this distance, the radar can only detect objects that are more than 25 ft (7.6 m) high, which means that Island A is shown on the radar but Island B is not shown. Remember that: the maximum detection range of the radar is limited by the curvature of the Earth's surface under normal conditions of wave propagation.

  • Page 22: Install The Radar Processor

    11.9 Install the radar processor Install the radar processor in a dry location away from spray, rain, drips, and condensation. The location site must allow you to easily connect the radar processor to the ship's ground, the interconnection cable, the power cable, and the 6000i and 6100i radar communications cable or the 8000i network cable.

  • Page 23: Wire The Radar System

    Wire the radar system Always install a separate circuit breaker or separate fuse for the radar system circuit. 12.1 Wiring guidelines Most installation problems are caused by shortcuts taken with system cables. When wiring the radar: DON'T make sharp bends in the cables. DON'T run cables in a way that allows water to flow down into the connectors.

Check that the interconnection cable is positioned so that you can easily connect it to the J connectors, as shown: Screw down the cable holders and clips to keep the interconnection cable in place inside the scanner. The interconnection cable must be clumped at the copper tape at location A.

  • Page 41: Calibrating The Radar

    14.4 Calibrating the radar You must calibrate the newly installed radar by adjusting the trigger delay and the heading calibration. To evaluate medium and short range returns, you are recommended to perform the calibration at sea in a normal operating environment and under fair weather conditions. There should be an area of at least 3 nautical miles forward of the vessel, containing known targets including the coastline.

  • Page 45: Maintenance

    Maintenance Before doing any maintenance work, always ensure that the radar system is turned OFF at the main power source. If a rectifier unit is used, turn OFF the power supply to this too. Remember that high voltages from the rectifier unit are always present, even if the radar is not operating, and these can cause severe injury or death.
