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.

Using shims to lower the main beam

D3229-3

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.
