摘要
激光通信抗干扰能力强、保密性好,非常适用于陆战条件下抗电磁干扰通信,对提升陆军作战能力具有重大推动作用。陆战环境复杂烟尘较重,发射的激光受到大气后向散射的影响会反射到己方的接收系统中,对接收产生一定影响,因此必须对激光通信系统后向散射的强度进行分析。根据陆战激光通信系统的特点,对收发独立口径和收发共口径的两类激光通信光系统大气后向散射进行了分析,并对系统发散角、接收视场、光轴间距等参数与后向散射强度的关系进行了仿真,为优化系统参数、减小大气后向散射对系统影响提供了参考。
Laser communication is characterized by anti-electromagnetic interference and security,it is fit for near-earth anti-electromagnetic communication and security-information transmission. The condition of land battlefield is complex and smoke heavily, the laser will be reflected to its own receiving terminal because of back scattering and have a strong impact on communication performance,it necessary to study the effect of back scattering on laser communication.For improving the performance of system, analyze the effect of back scattering on beacon and communication laser,then simulate the relation between intensity of back scattering and caliber divergent-angle receiving-filed axle-distance.It is reference for laser communication system of land battlefield.
