Abstract : This is a report of both analog and digital signal processing work performed in support of the AFAADS pulse-Doppler task. The basic elements required for the study of pulse Doppler, including a target-clutter simulator and a range-gated processing channel, have been developed. Curves are shown of the amplitude response, frequency response, and probability of false alarm versus threshold levels for the processing channel. This information is available for comparison with the digital approaches to pulse Doppler presently being studied. One digital technique is described which uses fast Fourier transforms to perform the velocity filtering or cross correlation required. The conclusion is drawn that the rapid advances in the digital field will result in the replacement of analog by digital techniques in many signal processing applications. (Author)
