我们描述了一种将雷达图像从明暗恢复形状与立体雷达测量相结合的技术，以使用多幅SAR图像生成地形表面模型。这项技术有望用于从麦哲伦的金星图像重建表面形状，并改进地面雷达测量的结果。地形坡度变化指示器中像素阴影的局部变化。像素明暗处理的这种变化为增加地形贴图的细节提供了机会。从明暗处理形状可以潜在地提供每个像素的相对高度变化。这导致了一组密集的高程测量，并更真实地再现了当地的地形形状
We describe a technique for combining radar image shape-from-shading with stereo radargrammetry to produce terrain surface models using multiple SAR images. This technique is expected to be of use to reconstruct surface shape from Magellan images of planet Venus, and to refine the results of terrestrial radar measurements. Local variation in pixel shading in an indicator of terrain slope changes. This variation in pixel shading offers an opportunity for increasing the detail of terrain mapping. Shape-from-shading can potentially provide a relative change in height at each pixel. This leads to a dense set of height measurements and a more faithful rendition of the local terrain shapes
