Abstract
The design and performance of a recirculating delay-line correlator employing a charge-coupleddevice high-density digital memory are reported. The operation of the processor is demonstrated when arranged as a matched filter and spectrum analyser for typical sonar waveforms. The processor permits rapid evaluation of system performance with changes in signal parameters, and resutls are presented which simulatethe effects of target Doppler on linear frequency modulation and linear period modulation
