Coincidence echo statistics
Original version
This report is not to be cited without prior reference to the authorAbstract
Two scatterers at similar range give an echo which may appear to be
due to a single scatterer. Methods for determining target strength that
depend on resolving single scatterers may fail in this instance. Statistics
associated with the described special case of coincidence are derived and
illustrated by theoretical computation for the SIMRAD ES38B, split-beam
transducer with 38-kHz operating frequency.
