    摘要:

    针对多机编队空对地激光制导精确打击时激光角度欺骗干扰问题,对多目标时指示激光信号的方位和编码特征进行了理论研究。结果表明:当指示激光信号时间差小于任一信号的重复周期且信号的重复周期为整数倍关系,或者指示激光信号时间差大于激光欺骗干扰设备解码时间时,激光欺骗干扰设备可以对组合信号进行解码,并分析了相应干扰方法。上述两种情况之外则会组合为伪随机序列码信号,激光欺骗干扰设备不能正确解码及实施干扰。

    Abstract:

    Aiming at the laser angle deception jamming to multi-targets of the multi-fighter group air-to-ground laser guidance attacking,the azimuth features and coding features of guide lasers on multi-targets was theoretical researched.The results show that the combined signal of guide lasers could be decoded by laser angle deception jammer,when the time difference of guide lasers less than the repetition cycle of any one guide laser codes,and all the repetition cycles has the relation of integer multiplication;or when the time difference of guide lasers longer than the decoding time of laser angle deception jammer,the relevant jamming methods of those two situations were discussed as well.Outside of those two situations,the guide lasers could combine to signal of pseudo random sequences code,then the laser angle deception jammer was unable to decode the combined signal or jamming.
