摘　　要：由于作用距离的不同,与空空导弹及反坦克导弹等激光引信相比,大气后向散射对弹道导弹激光引信的具体影响也不同。本文利用Mie散射理论计算了大气后向散射系数,通过数值计算分析了大气后向散射对弹道导弹激光引信的影响,探讨了消除大气后向散射影响的技术措施,以供相关课题的工程实施参考。Compared with laser fuse on air to air missile and anti - tank missile etc, the influence of atmospheric ba k scattenng on balhstic missile s laser fuse is different with that on laser fuse on air to air missile and anti - tank missile etc as the functional distance is different.The atmospheric back scattering coefficient was calculated using Mie scattering theory. The influence of atmospheric back scattering was analyzed through numeric calculation. Some techniques that may be used to eliminate the influence was discussed.
