B.0.0 Shifting from keel line

By shifting the scanner position from the keel line to the starboard side of the boat, it is possible to move shadow zones to the port side. This makes it possible to keep a clear view to the bow. The distance to be shifted can calculated using the following equation:

Ls = 0.4R+D/2 [m] (when R<15m)

Ls = 0.025R+D/2 [m] (when R>=15m) where Ls = distance to be shifted from keel line

D = diameter of obstacle on keel line R = distance from scanner to obstacle

B.0.1 Obtaining sufficient dip angle

Raise the scanner position so that there is a sufficient dip angle available between the line of sight from the scanner to the obstacle and the horizontal line. By raising the dip angle above 5°, it is possible to prevent mid- and long-distance shadow zones. The radar cannot detect objects below the line of sight.
