中文摘要：

有源干扰作为一种积极有效的干扰手段,使制导武器在攻击阶段收到大量的干扰激光信号而失去正确的目标信息,达到保护重点目标的目的。如何准确地对来袭激光武器激光信号编码信息实时分析与识别,已成为激光对抗的首要任务。在分析现有激光编码和波门设置特点的基础上,结合激光制导信号的时间相关特征,提出了一种基于自相关的激光制导信号脉冲编码信息识别技术,通过仿真、实验对该技术进行了研究,结果表明：该方法有效地解决了在尽可能短的时间内精确复制敌方激光编码的难题,为对抗的实施赢得了宝贵的时间,具有一定的理论和军事应用价值。

英文摘要：

As an effective interfering means, active interference makes the laser guided weapons lose the right object information to protect the important objects in the attack phase by sending much interfering signal. But how to intercept, capture, analyze and identify the laser guided signal code information real-time is the first task in the laser countermeasure. Based on analyzing the characters of existed laser coding and wave gate, as well as the time-correlation character of laser guided signal, the technique of laser guided signal information self-correlation identification was proposed and studied through simulation and experiment. The result shows that the technique resolves the difficult problem of copying the enemy laser signal in short time exactly. The feasible technique wins the time for the laser countermeasure, and has theory and military application value.
