摘　　要：根据光的粒子性,用蒙特卡罗法构建单个光子在大气传输中的散射模型,研究大气散射对激光角度欺骗干扰效果的影响。结果表明:①非对称因子、大气传输距离和消光系数等对干扰脉冲信号强度有不同程度的削弱,散射产生的迂回路径延迟了干扰脉冲到达导引头探测器的时间。②激光干扰脉冲在大气散射作用下脉冲展宽效应不明显。According to the particle properties of light,a scattering model of a signal-photon atmospheric transmission was built based on Monte Carlo method. Influences of atmospheric scattering on effects of laser-angle-cheat jam were studied. The results illustrate：（1）asymmetric factor,atmospheric transmission distance and extinction coefficient weaken the strength of pulse-jamming signal in different degree, circuitous path caused by scattering delays jamming pulse＇ s arrival in probe of seeker. （2）Broadening effect of laser-jamming pulse caused by atmospheric scattering is not obvious.
