7.4 Apply Imagery Processing Options
You can process sonar data by clipping the sonar image range or adjusting the rendering
options. These features do not affect the raw data in any way. SAMM's processing options are
fully available in acquisition, playback and load from directory modes. The processing features
available in post-processing mode are limited at this time.
7.4.1 Processing Controls
When in playback or acquisition mode, the
imagery processing options are available in
the Processing controls panel on the
sidebar (Figure 58 and Figure 59). The FLS
processing options are as follows.

Arc Coverage: Adjusting these values
trims the outer arc range of the FLS
imagery data. The minimum value will
clip from the port side of the FLS sector
and the maximum value will define the
trim from the starboard side. Values
are relative to the arc length of the
actual data (percentage).

Range Coverage: Adjusting these
values sets the inner and outer range of
the FLS imagery data to be used

Mosaicking options: SAMM can mosaic
data in ground range if altitude data is
available. Invert beams will flip the FLS
imagery and is useful for correcting
inverted installations. Check the boxes
to enable these options.

On the SLS (Sidescan) tab:

Clip: Adjusting these values trims the
SLS data to the specified minimum
and maximum ranges.

Normalization: Compensates for
backscatter variations due to system
beam-pattern
irregularities and
natural variation of backscatter with
