Mounting surface: power boats
On many small vessels the scanner unit can be installed on a mast platform, an
arch, or a bridge structure, but take care to follow the scanner site guidelines,
particularly regarding height. If necessary, construct a radar mounting platform
to obtain a sufficiently high mounting position. Make sure that the platform
surface is flat and the scanner unit drain hole (radome scanners) is not
obstructed. Ensure the platform is strong enough to support the maximum
shock loads likely to occur.
Setting the radiation plane
The scanner unit should be mounted so that the array rotates parallel to the
waterline. The radar beam is approximately 25° wide in the vertical direction,
providing good target detection during the vessel’s pitching and rolling.
Planing hull vessels, and some displacement hull vessels, adopt a higher bow
angle when the vessel is at its cruising speed. In many cases this substantially
alters and raises the radar’s main radiation plane, and can cause poor detection
of nearby targets. It may be helpful to lower the radar beam back towards the
parallel, by shimming the rear of the radar, so that the beam points slightly
downwards with respect to the waterline when the vessel is at rest.
The shims may be made from aluminium plate wedges, simple flat washers, or
an angled wooden block. For thick shims, you may need longer securing bolts
than the M8x40 bolts supplied with the radome scanner, or the M10 studding
supplied with the open array scanners.
