摘要
以使用了插入随机脉冲伪随机码的激光指示信号为研究对象,提出随机脉冲滤除技术.在研究解决时间相关性判据的基础上,利用计算机仿真技术对该技术进行仿真研究.仿真结果表明:该技术可以有效地滤除激光指示信号中插入的随机脉冲信号,滤除概率大于99%,且将激光指示信号当作干扰信号滤除的概率基本上小于5%.因此能保证大多数情况下可以根据滤除后的激光信号产生有效的激光欺骗干扰信号.
The paper mainly discussed the laser-indication-signal which inserted with the random-pulse and gave the technology to filter the random-pulse.With the help of computer-simulation-technology which based on the time-related-criteria,the technology to filter the random-pulse was studied.The result of simulation showed that the technology could filter the random-pulse inserted in the laser-indication-signal effectively,the probability of filtering the random-pulse was above 99% and the probability of mistaking the laser indication signal for the interfering pulse was less than 5%.Therefore it could be ensured that in most cases,effective laser deception jamming signals could be produced by filtered laser signal.
