摘要
激光角度欺骗干扰信号超前制导信号的时间决定了激光导引头是否将干扰信号当作制导信号处理,从而决定了激光角度欺骗是否有效。从探讨激光角度欺骗干扰信号能够进入激光导引头波门且超前制导信号的概率出发,利用激光制导武器光电干扰仿真系统,仿真得到了激光角度欺骗干扰概率与时间超前量之间的关系。研究结果表明:当时间超前量小于波门宽度的1%时,才能保证激光角度欺骗干扰有效。
The laser-angle-cheating jam is valid if the seeker of laser-guiding-weapon mistakes the jamming signal for the laser-guiding-signal and the ahead-time between the jamming signal and the laser- guiding-signal affects the jamming efficiency of laser-angle-cheating jam. The relation between the a- head-time and the probability of jamming signal which is in the wave-door of laser seeker and is ahead of the laser-guiding-signal was calculated by the photoelectric jamming simulation system of the laser guided weapon. On the base of the simulation software of laser guiding weapon trajectory, the best a- head-time was researched. The result indicates that if the ahead-time is less than 1% of time width of wave-door, the laser-angle-cheating jam is valid.
