1. A receiver in a radar system having a transmitter for producing pulses to be radiated by an antenna, the receiver comprising:

  • means responsive to a transmitter produced pulse for performing complex demodulation of a waveform corresponding to the produced pulse;

    means responsive to the complex demodulated waveform corresponding to the produced pulse for forming a filter representative of the pulses produced by the transmitter;

    means for receiving a return signal corresponding to each pulse produced by the transmitter from the antenna;

    means for performing complex demodulation of the return signal; and

    means for correlating the complex demodulated return signal with the filter representative of the pulses produced by the transmitter.
