摘　　要：针对单天线调频连续波雷达发射信号泄漏问题,结合数字自适应系统数据处理能力强、准确灵活、通用能力强等优点,提出了数字对消技术方案,并进行了仿真分析和实验验证,结果表明,该方案能有效抑制由于收发隔离不足导致的发射信号泄漏问题。In view of the single antenna FMCW radar transmitter signal leakage, this article proposes a digital cancellation technology combining with the advantages of the digital adaptive system such as good data processing ca- pability, accuracy, flexibility and universality. Simulation and experiment results shows that the program can effec- tively suppress the emission signal leakage problems caused by inadequate transceiver isolation.
