  • Factored matched filter/FFT radar Doppler processor
    Patent number: 4622552
    Abstract: A factored matched filter/FFT radar Doppler processor for reducing the le of clutter components contained in radar signals. The processor includes a matched Doppler filter, having a filter response matched to the spectrum of the clutter components, through which the radar signal is passed. The filtered output of the matched filter is further filtered by a coherent integration filter to further reduce the level of the clutter components.
