A digital leakage cancellation scheme for monostatic FMCW radar
A novel heterodyne scheme based on real-time digital signal processing is proposed for leakage cancellation in monostatic frequency modulated continuous wave (FMCW) radars. Compared to conventional analog implementation, the advantages of the proposed scheme include that the DC offset existing in analog mixers affecting the cancellation performance are eliminated. A radar test bed at 26 GHz has been built. The measurement results show more than 40 dB suppression in transmitter leakage, which proves the effectiveness of the proposed approach.
