摘要： A 3D rendered image of a radar-scanned terrain surface is provided from a radar return signal from the surface, wherein the return signal includes data indicative of azimuth, elevation, and range of a radar-illuminated area of the surface. The data are processed for transformation into X, Y, and Z coordinates. The X and Y coordinates corresponding to each illuminated area are triangulated so as to create a mesh of triangles representing the terrain surface, each of the triangles in the mesh being defined by a vertex triplet. 3D imaging information (grey scale shading and/or coloring information) is added to each triangle in the mesh, based on the amplitude of the radar return signal from the coordinates represented by each vertex in the triplet and the value of the Z coordinate at each vertex, so as to form the 3D rendered image.

摘要翻译：雷达扫描地形表面的3D渲染图像是从表面的雷达返回信号提供的，其中返回信号包括指示表面的雷达照明区域的方位角，仰角和范围的数据。处理数据以转换为X，Y和Z坐标。对应于每个照明区域的X和Y坐标进行三角测量，以创建表示地形表面的三角形网格，网格中的每个三角形由顶点三元组定义。基于由三重态中的每个顶点表示的坐标的雷达返回信号的幅度和每个三角形中的Z坐标的值，将3D成像信息（灰度阴影和/或着色信息）添加到网格中的每个三角形顶点，以形成3D渲染图像。
