1. A CW radar range measuring system, comprising:

  • a transmitter for transmitting a continuous wave radar signal phase encoded in accordance with a transmit code;

    an analog to digital converter section for converting a sequence of samples of the radar return into a corresponding sequence of digital words;

    a receiver adapted to receive a radar return from the transmitted radar signal, such receiver comprising;

    a receive code generator for storing a replica of the transmit code and for producing differently time delayed replica of such transmit code, such differently time delayed replica being produced a predetermined time after the phased encoded radar signal is transmitted;

    a digital correlator/integrator fed by the digital samples produced by the analog to digital converter and the receive code produced by the receive code generator, for generating a plurality of range channels and for providing an indication of radar return energy as a function of range from the transmitter for each of the channels.
