dc.description.abstract | Often it is necessary or desirable to perform a standard-target calibration
at rather short range, for example, because of shallow water or interest in
measuring animals at short range. A number of general range-dependent effects
may prove especially troublesome at short range. These include effects connected
with (1) time-varied gain or similar range compensation, (2) finite size of the
target, and (3) pulse repetition frequency. The origins of these effects are
reviewed and, where particular to a specific system, illustrated by reference to the SIMRAD EK500 echo sounder. | no_NO |
