调幅式调制盘导引头干扰原理分析及验证

摘要

介绍了调幅式红外导引头的工作原理，并进行了激光对调幅式红外导引头的干扰原理分析。激光干扰作用是通过扰乱跟踪处理器使导弹失去其跟踪目标。结果显示干扰信号频率对干扰效果影响很大。通过中红外激光对红外导引头干扰实验验证了理论分析的正确性。%The principle of infrared seeker with amplitude modulation reticle is introduced,and laser jamming effect on infrared seeker with amplitude modulation reticle was analyzed. The function of laser jamming is to cause the missile to miss its intended target by disturbing tracking process of the seeker. The results show that the jamming effect is greatly influenced by the frequency of the jammer signal. Finally,the correctness of the principle analysis is validated by the experiments.
