Laser pulse coding is one of the anti-jamming measures for laser-guided weapons.The laser-angle cheating jamming and the high-repetition-frequency laser jamming are the main sources of jamming for semi-active laser-guided weapons.To study the effect of different encoding methods on the anti-angle-cheating jamming performance and the anti-high-frequency laser jamming performance of semi-active laser terminal guidance weapons,the auto-correlation function and normalized cross-correlation function quantized methods were presented,which were concerning to the decoding algorithm of the enemy laser warning equipment and the decoding process of our seeker.In this paper,during the simulation on the main coding methods,the results show that the ability of anti-angle-cheating jamming of laser pulse coding is affected by the periodicity of coding sequences and the randomness of pulse interval;and the ability of anti-high frequency jamming of laser pulse coding is affected by the randomness of pulse interval;and the anti-angle-cheating jamming and anti-high frequency jamming effects on LFSR status coding are better than other coding methods.
