They also define the range of target samples which are used for Fourier transformation
to create the target strength frequency response (the curve in the
TS(f) information
pane) and the target position phase values.
Increasing the distance values will require the targets to be further separated, but can
increase the frequency resolution for the target strength frequency response (in the
TS(f) information pane).
The value for the
Distance After Target
should normally be larger than the value for
Distance Before Target
due to the backscattering properties of a target. The values
are specified in meters and are applied on the matched filtered/pulse compressed
sample data.

may be inaccurate. Once you are able to assess your catch, you can use the
Fish Size
