雾粒子散射对激光制导的影响研究

为了研究雾粒子散射对激光制导的影响,提高制导武器的制导精度。基于Mie理论,考虑粒子尺度分布函数,得到了群体粒子散射模型,在该基础上,建立了目标方位偏差角与散射光强的关系式,从粒子散射的角度分析了粒子散射光强对回波信号的影响。计算表明,大气粒子在一定的尺度分布状况下的后向散射光强对回波信号的影响比较明显。该研究结果为大气微粒后向散射对制导的影响研究提供了参考。

Study on scattering of fog particles impact laser-guided

It is the very important problem to all control and guide weapon that how to increase the precision of control and guide ,but the atmosphere scattering is one of the important factors the precision of control and guide. This paper set out from Mie’ s theory and based on the model for scattering in particles, a formula is present for warp azimuth of target and scattering intensity, it provides the reference for the atmosphere backscattering affects the precision of control and guide.
