1. A radar system that provides for near range detection of targets for use with frequency modulation continuous wave (FMCW) and stepped frequency waveforms, said system comprising:

  • transceiver means for transmitting reference ramp signals and receiving reference ramp return signals; and

    signal processing means for;

    (a) determining a coherent average of the received reference ramp return signals;

    (b) subtracting a coherent average of the transmitted reference ramp signals from each signal in a group of succeeding reference ramp return signals; and

    (c) noncoherently integrating the resulting group of reference ramp return signals to provide for detection of nearby targets; and

    a display for displaying detected targets.
