Abstract

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.

单站FMCW雷达的数字泄漏抵消方案

提出了一种基于实时数字信号处理的单稳态调频连续波(FMCW)雷达泄漏消除外差方案。与传统的模拟实现相比，该方案的优点包括消除了模拟混频器中存在的影响对消性能的直流偏移。已建成26 GHz雷达试验台。测量结果表明，该方法对发射机泄漏的抑制作用可达40 dB以上，证明了该方法的有效性。
