tilted sonar array. These settings change in a non-linear manner. See
for a more detailed discussion of this feature.
5.7.1 Apply a Filter (Filter)
Determines whether or not a filter is applied to the bottom-detect process. The
options are:
Range:
Applies minimum and maximum range values as entered in the
“MinRange” and “MaxRange” fields.
Depth:
Applies the minimum and maximum depth values as entered in
the “MinDepth” and “MaxDepth” fields.
Both:
Applies both the range and depth minimum and maximum values.
None:
No filters are activated.
5.7.2 Set Range Filter Limits (MinRange / MaxRange)
Only bottom returns within these range limits will be used in the bottom detection
process.
5.7.3 Set Depth Filter Limits (MinDepth / MaxDepth)
Only bottom returns within these depth limits (depth gates) will be used in the
bottom detection process. Use of a motion sensor is required to maintain
constant depths during the ship‟s normal pitch and roll action.
5.7.4 Correct for a Tilted Sonar Array (HeadTilt)
The value entered here rotates the layer formed by the depth gates. Use this
function to compensate for a sonar array with a roll offset in its mounting
structure. The adjustment range is plus or minus 180
in 1
steps.
