A Matched Filter Doppler Processor for Airborne Radar.

Abstract

The airborne radar presents noteworthy problems of clutter cancellation because of platform motion. The returns from fixed objects must be filtered out as clutter. A matched filter signal processor design is presented that produces the necessary level of clutter rejection. The results are compared to various processor configurations, e.g., moving target indicators (MTIs) cascaded with a matched filter processor, displaced phase center antenna (DPCA) cascaded with a matched filter processor, the fast Fourier transform (FFT), and MTIs cascaded with the FFT. The processors are compared on the basis of their clutter rejection, signal processing losses, and minimum detectable velocity (MDV) capabilities. (Author)
