摘　　要：利用三角形小平面模型、修正的几何光学模型与γ-f角度截断后向散射系数模型和沙漠场景的数字高程模型数据,对沙漠场景下地杂波雷达散射截面进行了仿真。散射特性模型结合场景几何模型计算得到的场景RCS矩阵图表明,仿真结果与沙漠场景特殊的地形特性和周期性特征基本符合,验证了该方法的有效性。Simulation of desert scene for land clutter radar cross section （RCS） is investigated in the paper, based on triangular facet model, an angular cutoff model of revised GO Model and γ-f Model for backscattering coef- ficient and Digital Elevation Model （DEM） data of desert scene. The RCS matrix charts obtained by scattering char- acteristic model and geometric model of the scene demonstrate that the simulation results coincide mainly with special terrain features and periodic characteristics of the desert scene. The validity of the proposed model is then obtained.
