ACTIVE SONAR USAGE

Version 3
With the input from a motion sensor (and
roll stabilization enabled) to steer each
receive beam dynamically for every
sample, the swath stays vertical
irrespective of vessel motion thereby
maximizing swath.

It is recommended that the motion sensor data update rate is at least 50Hz and
preferably 100Hz. Baud rate and protocol details may be set in the Configure Motion
Sensor dialog (see
section 4.2.7 Motion ), but it should be ensured that the baud rate is
sufficient to allow the desired update rate.
Monitor motion data and roll history on the Motion tab (see
section 5.4 Motion Tab ).
6.3.3 Head Tilt
In certain applications it is desirable to physically rotate the sonar head. Instances of this
are pipeline surveys where a dual head normally mounted on an ROV are inclined
inwards to maximize the number of hits on a pipe. Another application is survey of
harbor walls where the desire is to survey as close to the waterline as possible.
For instructions on head tilt configuration, see
section 4.2.3 Hardware Configuration .
