An initial investigation has been made into those characterizations of the strength of sonar target echoes that are relevant to mobile tactical sonars. The primary focus of the investigation is on the statistical characterization of echos, in a format compatible with applications to studies of sonar design and utilization and to mathematical modelling and scaled physical modelling of targets. The sonars whose performance is considered are those characterized by the following chain of elements signal generator, beamformer, filter possibly matched filter or correlator, envelope detector and squaring or equivalent, post-detection integration, decision and display. The parameters of these elements e.g., resolution time, averaging time are not specified.
