摘要

摘要: 圆迹干涉SAR具有对场景目标进行全方位观测测量的优势，为了满足高分辨率圆迹SAR成像对高精度的场景数字高程模型(Digital Elevation Model, DEM)的需求，该文提出了一种基于圆迹干涉SAR数据的高程估计方法。首先推导了采用后向投影(Back Projection, BP)算法时的圆迹干涉SAR信号模型，然后给出了基于圆迹干涉SAR处理的场景DEM提取流程，最后通过仿真实验验证了所提方法的有效性。

Abstract: Since Interferometric Circular SAR (InCSAR) has the advantage of all-directional observation, a method for Digital Elevation Model (DEM) extraction based on InCSAR is proposed to ensure the high accuracy of the high resolution Circular SAR imaging. Firstly, the signal model of InCSAR is presented when Back Projection (BP) processing is adopted for SAR imaging; secondly, DEM extraction based on InCSAR is proposed; thirdly, the proposed method is validated by the simulation test.
