摘　　要：收发隔离是许多电子干扰系统中的关键技术,若隔离度不够,干扰发射信号耦合进入侦察接收机,使干扰机不能正常工作甚至产生自激。利用耦合通路的线性非时变性,采用自适应滤波器对耦合通路辨识来实现噪声对消,仿真结果表明,该方法能有效抵消反馈干扰,满足提高隔离度需要。Transmitter Receiver isolation is a key technology in many jamming systems. If the degree will couple to the receiver, and then the jam will be unaexcitation. The coupling channels＇linear time invariable identify coupling channels and to carry out noise cancellamethod can cancel feedback noise, which meets the re- quirements of higher isolation.
