摘要
以作战平台的通信系统为背景,分析了阻塞干扰的形成机理及其对于接收机的危害,指出了几种传统解决方法的不足,在此基础上提出了应用自适应干扰抵消技术解决阻塞干扰的方法。该方法利用矢量合成的方法控制取样信号的幅度和相位,在接收端与干扰信号相互抵消。最后讨论了自适应干扰抵消系统实现过程中可能遇到的问题。
The formation mechanism of barrage jamming and its damage to receiving antennas was analyzed according to the background of communication systems on operational platforms. Based on which, a solution to the problem using adaptive interference cancellation technique was put forward. Sampled signal was adjusted by vectorial resultant, and then combined with the received signal to cancel the interference. Some problems may encountered in realization of adaptive interference cancellation were discussed.
