摘　　要：弹道导弹突防雷达干扰机采取主瓣干扰时,收发同时工作十分必要。通过计算干扰机收发信号功率,分析了影响收发隔离的因素,指出采用收发功率自适应措施可降低收发隔离要求。然后给出了一个实现收发功率自适应控制的电原理参考框图,指出收发天线前后分置是解决收发隔离的一种有效方法,介绍了2种降低波导天线尾瓣增益的方法。最后指出了探讨的方法虽然原理上可行,但在实际工程应用中还有许多实际问题需要解决。When ballistic missile（BM） penetration jammer takes the way of interfering the antenna＇ s main lobe, it is necessary for BM penetration jammer to receive and transmit signal at thesame time. Through computing the power of receiving and transmitting signals of BM penetration jammer, the main factors effecting isolation between receiving and transmitting of BM penetration jammer is analyzed and it is found that the receiving and transmitting power self-reacting control can decreasethe isolation request between receiving and transmitting. Then, an electric principle drawing realizing receiving and transmitting power self-reacting control is proposed, and to separate transmitting and receiving antenna in the front and the rear respectively is an effective method to solve the problem of isolation between receiving and transmitting. In addition, two ways of decreasing wave-guide antenna rear lobe gain are introduced. Finally, it is pointed out that the method is feasible in theory, but there are many problems to be solved in practical engineering application.
