摘要
激光角度欺骗干扰是对抗半主动激光制导武器的有效手段,为提高激光导引头的抗干扰效能,在研究激光导引头实时型波门技术的基础上,引入了对波门实施对称收缩和附加偏置量两种控制策略,考虑到干扰信号在导引头波门的出现在时域上服从正态分布的规律,构建了激光导引头波门录取干扰激光信号概率的计算模型.采用控制变量的方法对干扰激光信号超前量、导引头波门宽度、控制收缩比和偏置量对干扰有效概率的影响进行了研究.结果表明:采用超前同步干扰时,不同波门宽度均存在一个与之对应的最佳干扰超前量使其干扰有效概率最大,对波门设置合理的等比收缩系数和附加偏置量,均能有效降低导引头录取干扰激光信号的概率,提高导引头的抗干扰性能,可为激光角度欺骗干扰实装对抗效能研究提供技术支撑.
Abstract
Laser angle deception jamming is an effective means to anti semi-active against laser guided weapons.In order to improve the anti-jamming efficiency of the laser seeker,based on the study of the real-time wave gate technology of the laser seeker,two control strategies of symmetrical contraction and biasing contraction for the wave gate are introduced.A calculation model of the effective probability of the jamming laser signal which accepted by the laser seeker wave gate,the jamming laser signal appears in the wave gate which obeys the normal distribution is also taken into account.The influence of jamming laser signal advance time,the wave gate width,the control contraction ratio and biasing value on the effective jamming probability is studied by using the method of control variables.The simulation results show that when the advanced synchronizing interference is adopted,there is a corresponding optimal jamming lead for different wave gate widths which can achieve the maximum effective probability of jamming signal.By setting reasonable isometric contraction coefficient and biasing value for the wave gate can effectively reduce the jamming probability and improve the anti-jamming performance of the seeker,Which can provide technical support for the research on the effectiveness of laser angle deception jamming.
