FLIR Raymarine HD DIGITAL RADOME, Installation Instructions Manual

Page: 23 / 64

Planing hull vessels, and some displacement hull vessels, adopt a higher bow angle when the vessel
is at cruising speed. This may raise the radar’s main radiation angle, and can cause poor detection
of nearby targets. It may be necessary to compensate for the bow rise to ensure optimum target
detection. This can be achieved by fitting a wedge or washers between the mounting platform and
the base of the radar scanner, so that the radar beam remains parallel to the water line when the
vessel's bow rises at cruising speed.
