<p>A receiver (10) for active sonar systems comprises two fundamentally different detection processors (100,200) operating simultaneously with the output of each detection processor (100, 200) being combined by a computer (40) utilizing a computer-aided detection algorithm. One detection processor (100) includes a segmented replica correlator (SRC) (14) and the other detection processor (200) includes a polarity coincidence correlator (PCC) (15). Each detection processor (100,200) provides to the active computer-aided detection algorithm a list of ranges and bearings of a relatively small number of detection events. The computer algorithm operates on these events to compare events from the current ping and the previous ping for each of the processors (100,200).</p> |
