本文针对激光制导武器的制导特点，分析了其可能采用的抗干扰措施，认为主要有两种手段，一种是将引导信号做成编码信号，另一种是在导引头上设置脉冲录取波门。分析了几种很可能被采用的脉冲编码技术、认为伪随机码将在制导信号中得到广泛应用，并根据有源干扰的要求，给出了几种编码的识别方法。 In this paper, guided by the characteristics of laser-guided weapons, anti-jamming measures may be analyzed, that there are two main means, one is to make the pilot signal encoded signal, and the other is set in the seeker pulse admission wave door. Several possible pulse coding techniques are analyzed. It is considered that the pseudo-random codes will be widely used in the pilot signals. According to the requirement of active interference, several coding methods are given.
