摘要
干扰超前量的设置对激光角度欺骗干扰的成功概率有着重要的影响。通过建立激光角度欺骗干扰中制导信号和干扰信号被波门录取的概率模型,推导并验证了最优干扰超前量公式。通过仿真研究了不同影响因素对最优干扰超前量设置的影响。仿真结果表明:波门宽度、制导信号脉冲间隔误差、干扰信号脉冲间隔误差对最优干扰超前量的设置均有较大影响。最优干扰超前量与波门宽度成正比,制导信号脉冲间隔误差越大、干扰信号脉冲间隔误差越小,最优干扰超前量越大。设置合适的干扰超前量可以大幅度提高激光角度欺骗干扰的干扰概率。
Abstract
The setting of the jamming lead has an important influence on the success probability of laser angle deception jamming. By establishing the probability model of the guidance signal in the laser angle deception jamming and the probability model of the jamming signal being accepted by the wave gate, the optimal jamming lead formula was deduced and verified. The influence of different factors on the optimal jamming lead setting was studied by simulation. The simulation results show that the gate width, the guidance signal interval error and the jamming signal interval error have great influence on the setting of the optimal jamming lead. The optimal jamming lead is proportional to the width of the gate. The larger the guidance signal pulse interval error is, the smaller the jamming signal pulse interval error is, and the larger the optimal jamming lead is. The jamming probability of laser angle deception jamming can be greatly improved by setting the appropriate jamming lead.
