Abstract: A cancellation technique embodied in a system and a radar signal processing method that is employed to detect near-range targets. The present invention uses a frequency-modulation continuous-wave (FMCW) or stepped frequency waveform and is capable of detecting near-range targets that would normally be obscured by transmitter leakage and internal reflections. This cancellation technique works by transmitting one or more reference ramp signals and then subtracting the coherent average of the transmitted reference ramp signals from a group of succeeding transmitted and received ramp return -signals. The resulting group of FM ramp return signals is noncoherently integrated to achieve more stable target detection statistics. More particularly, the present technique implements the following processing steps. Generating a predetermined number of reference ramp signals. Coherently averaging target return signals corresponding to transmitted reference ramp signals to produce a reference average signal.
