High performance time compression systems using fast frequency-domain correlation

Correlation processing for active sonar systems is discussed. The systems described use 32-bit complex vector processor (CVP) ASIC, high-speed dual port memory and a writable control store architecture to provide sustained data throughputs up to 25 million correlation points per second. This is sufficient for many sonar (and indeed some radar) applications. Two basic systems are outlined, one a single 6U PCB system using a single CVP for lower throughput systems, the other a two board, 8 CVP systolic pipeline processor supporting throughputs up to 25 million correlation points per second
