摘要：
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. ©, 2015, Science Press.
