一种半主动激光制导双脉冲伪随机码设计

Design of Double Pulse Pseudo Random Code for a Semi-active Laser Guidance

激光编码是激光半主动制导武器抵抗激光有源干扰的重要措施,从抗干扰角度出发,设计了一种新的编码--双脉冲伪随机编码,给出了一种软硬件相结合的译码方法,并对该种编码的抗干扰性能进行了理论分析。分析结果表明:编码中的伪随机编码可用于抗激光欺骗干扰,双脉冲设计可用于抗高重频激光干扰,译码整形后的方波脉冲宽度越窄,抗高重频干扰的效果越好。

Laser encoding was an important measure for semi-active laser guided weapon to resist laser active jamming.Starting from the angle of anti-jamming,a new encoding named double pulse pseudo random code was designed.A decoding method combining hardware and software was presented,and the anti-jamming capability of the code was analyzed in theory.The analysis results indicate that the pseudo random code can be used to resist laser deception jamming,and the double pulse design can resist high repetition frequency laser interference.The narrower the square pulse width of decoding after shaping,the better effect of anti high repetition frequency interference.
