1. An FM-CW radar processing system which transmits an FM-CW wave and receives a reflected wave from a target object, comprising:

  • a modulating signal generating unit capable of changing a modulating signal to be applied to said FM-CW wave;

    a pairing unit for pairing peak signals between an up portion and a down portion of said FM-CW wave;

    a calculating unit for calculating a distance or relative velocity with respect to said target object, based on the peak signal in said up portion and the peak signal in said down portion obtained by said pairing; and

    a comparing unit for comparing said distance or relative velocity, obtained by said calculating unit after changing said modulating signal, with said distance or relative velocity obtained before changing said modulating signal.
