分析了高分辨率SAR图像中建筑物的成像特征:叠掩及角反射器效应,获取了SAR图像中建筑物屋顶像点位移,最后根据相应的公式计算了建筑物的高度。与实际高度数据相比较,发现计算结果精度较高,是一种可行的建筑物高度获取方法,可为以后发射的高分辨率星载SAR图像的应用提供很好的借鉴。

This paper analyses the layerover and corner reflection effects of building in high-resolution SAR image.The height of building is computed from layerover of building,based on the corresponding formula.By comparing the extracted height with the real height of buildings,the precision is high and this method is a good idea.Our method is a use for reference to extract some information from future high-resolution satellite-borne SAR image.
