Abstract
An active sonar system, a method associated therewith, and a computer-readable medium associate therewith, each provide a method of sonar signal processing. The method includes receiving a plurality of initial detections of a target and associated initial detection times, associated with sound transmitted at a pulse rate interval (PRI), and associated with received sound including echoes from a target. The echoes result from the transmitted sound. The method also includes analyzing the plurality of initial detection times with a pulse sorting transform configured to identify periodic PST detection times within the plurality of initial detection times that are equally spaced in time and that are representative of the echoes from the target.
