摘　　要：无论沿海或远洋,蒸发波导现象的存在使雷达传播变得复杂。在蒸发波导确定且其散射特性固定条件下才能精确描述微发射角雷达电磁波特性。利用拉曼激光雷达模型,对不同的大气环境进行研究和分析,得到所需的高精度海上蒸发波导特性。The propagation of radar in the presence of the evaporation duct has proven to be a difficult problem in both littoral and open ocean environments. To properly characterize the propagation of a radar beam at low elevation angles, the evaporation duct must be located and scattering properties quantified. A Raman lidar model is used to examine the expected accuracy for evaporation duct over sea. The simulation also allows various atmospheric scenarios to be investigated and analyzed.
