The Triangle Array - RADAC WaveGuide 5 Direction User Manual

The Triangle Array

The triangle array consists of three radars placed in vertical positions, typically about 3 to
6 meter apart. It can be challenging to find a good mounting position for the triangle array
on an offshore platform. On the other hand, from the perspective of retrieving the strongest
radar reflections, this is the optimal configuration for large mounting heights (above 45m).
As with the other array configurations, radars A, B and C are defined by their serial
number as indicated on the type plate. The mounting positions of radars A, B and C must
be anticlockwise when looking from above (as shown in Fig. 2.9). The user-interface allows
the user to customise the used configuration.
A mounting plate can be used to fix each radar to two horizontal beams at the desired
location (an example sketch of such a plate is given in Fig. 2.10). Upon request, Radac can
supply this mounting plate (product no. WG5-MP-EX). During installation it is advised
to install the mounting plates first and secondly install the radars.

bered A,B and C in an anticlockwise sequence.
