摘　　要：大气波导传播可导致电磁波的传播路径和有效覆盖范围与正常折射条件下明显不同,这会影响雷达的探测性能和部署。文中借助于抛物形波方程,研究了雷达系统参数的设置对3种典型波导环境下电磁波单程传播损耗的影响,并对雷达探测性能做出评估,给出了建议,为以后雷达回波资料反演大气折射率廓线作必要的准备。Atmospheric duct could cause the electromagnetic wave propagation paths and effective coverage area to be different from that of the standard refraction conditions, thus affecting the performance of radar detection as well as its deployment. Using parabolic wave equation, the performance of radar detection in the presence of three typical atmospheric duets is studied in terms of changing its system parameters. Some conclusions and sugestions are given, which prepares the future research on inversion for refractivity parameters from radar echos.
