A.3 Offsetting the Sonar Array
In the case of a sonar array mounted so as to look at a river bank or under a
wharf structure, this discussion assumes a thirty degree offset to starboard. If the
offset value of this mounting configuration is not identified properly, the ends of
the swath may be cut off by one or both of the depth gates intersecting the
bottom display even when a motion sensor is used.
