摘　　要：针对转发式干扰过程中干扰信号进入接收机而造成系统不能正常工作甚至自激的问题 ,提出应用自适应干扰对消技术 ,可以消除干扰保存有用信号 ,以达到提高干扰机收发隔离度的目的。In the process of repeating type jamming, the interference signals always enter into the jammer receiver to make it work abnormally even cause self excitation. The adaptive interference cancellation is suggested to solve this problem. Taking advantage of it, the interference signals are cancelled, the useful signals are saved, and the transmitter-receiver isolation of the jammer is improved. The validity of this scheme is proved by simulation.
