The concern of this paper is the Single Pulse Resolution Filter - SPRF, which is capable of esolving near-rectangular overlapping pulses. The reason for assuming such pulses is that despite the attractive properties of matched filter pulse compression most operational sonar systems continue to use a finite-length rectangular pulse of constant frequency. The task of the SPRF in such system is to improve the short-range resolution and the target detectability in reverberation. The SPRF here
