SECTION 1 OVERVIEW

The proper installation of the radar equipment is critical in ensuing its effective and reliable performance as well as facilitating maintenance and repair. Therefore, carefully install the radar equipment by following the procedures below: 1) Install the scanner as high as possible while taking the scanner's weight into consideration. 2) It is preferable to install the display unit in the wheel house to facilitate observations. 3) The standard cable length for installing the radar JMA-5300 is as shown in the table below. If there is a need for using a cable longer than the standard length, notify JRC of it beforehand. A cable longer than the standard length may hider performance of the radar, so give it careful consideration when planning the installation. (The standard cable length is considered to be sufficient for small and middle size ships for which this radar is designed.)

2.1

SELECTING THE INSTALLATION POSITIONSelect the scanner installation position by taking into consideration the following:

1) Determine how high the scanner can be installed on the hull by taking the scanner's weight into consideration. 2) The scanner installation height has a direct relation to the maximum detectable range. The higher the scanner is located, the wider the detectable range becomes. However, if it is too high, at positions higher than the vertical beam width (-3 dB point), the energy of radio waves significantly attenuates, thus making it difficult to acquire a target located at close range. Additionally, the scanner is greatly affected by sea clutter. Therefore, install the scanner according to its weight, maximum cable length and maintenance. For relationships between the scanner installation height and the maximum detectable range, refer to "Radar Wave with the Horizon" in section 6.1 of the instruction manual. 3) If the width of the radiation beam in the vertical direction is set at 2 degrees (i.e. most radiation energy centralizes within this angle), the energy of radio waves is very weak in directions beyond 2 degrees. If a scanner position is too high, it is difficult to acquire a small target located at close range. Yet, if the scanner's position is low, it is difficult to acquire a distant target, and the ship's mast, derrick, and chimney obstruct radiation beams, thereby reducing the radar's effective range. Generally, the lowest position for installing a scanner is considered to be the AB line in Fig.2.1. In the radar JMA-5310/5320, 2 is 20 degrees, and in the radar JMA-5330, 2 is 30 degrees. A scanner position is usually determined at a high enough level so that the chimney and the shrine-gate type mast are out of the range where radiation beams are radiated.JMA-5310/20: =10 JMA-5330: =15

SELECTING THE INSTALLATION POSITION

4) A scanner's plane position is generally determined so that the shadow of the radio wave due to the mast does not overlap with the fore-and-aft line. If there is no large obstacle ahead, the scanner is usually installed on the fore-and-aft line on the wheel house. 5) Avoid the installation of a bearing finder VHF antenna near the scanner, because this causes noise in the radio equipment and a trouble with radiated radio waves. 6) If the scanner's radiation plane is contaminated by smoke and soot from the chimney, the radar's performance will decrease. Therefore, consider ease of maintenance when determining the scanner's position and the structure of the mast and the tower.

7) If the halyard for the signal flag is located in the vicinity of the scanner, wind may cause the flag or halyard to wind around the scanner's radiator, resulting in failures. So, carefully consider the location before installing the scanner. 8) Since the derrick post has a great amount of vibration, it is not suitable as a location for the scanner installation. 9) Taking into consideration the swing circle (d), keep a sufficient distance between the scanner and other installed object (e.g. mast or radio antenna) so that there is d/2 + 200 mm or more from the scanner's rotation center. The swing circle of the scanner for the radar JMA-5300 is as shown in Table.2.
