radars labeled A, B and C.
In some cases it can be decided to mount the three radars in
line with each other, for example when mounting them to the
railing of an o
ff
shore platform. This installation is called a line
array. In this case the central radar needs to be tilted to obtain
a triangular reflection footprint, which is illustrated in Fig. 1.7.
In a line array, the tilting definitions (Fig. 1.3) require that
radar A is positioned between radar B and C. This allows tilting
radar A away from the line B-C and by doing so forming a
triangle with the radar foot prints on the water surface. The
direction of the radar tilt angle is defined with the right hand
rule as shown in Fig. 1.7.
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. 1.9). Upon request, Radac can
supply such a mounting plate (product no. WG-MP-SS). During installation it is advised
to install the mounting plate first and secondly install the radar.
Upon request, Radac can supply an optional frame (product no. WG-MH-SS) that allows
for mounting a radar at angles 0, 5, 10, 15 and 20 [deg] with the horizontal plane shown in
Fig. 1.8). Each frame includes a mounting plate.
