1. A radar system comprising:

  • a transmitter for generating a predetermined number of electromagnetic pulses;

    a receiver;

    a signal processing system operatively connected to the receiver and configured to identify return signals associated with a target, and determine the radial velocity of the target; and

    a phase processor responsive to the signal processing system and configured to;

    extract phase data as a function of time from a received return signal associated with the target,convert the extracted phase data to the frequency domain,analyze the converted phase data to identify phase changes indicative of a type of motion of the target,wherein the phase changes indicative of a type of motion are independent of phase changes indicative of the radial velocity of the target.
