Theoretical analysis and Applications of Tomographic SAR Imaging

摘要

Tomographic Synthetic Aperture Radar extends the traditional 2D SAR imaging to multi dimension imaging by reconstructing the real scene of SAR sensor on the ground. It is very important to realize the 3D mapping of urban areas, the identification of artificial targets and so on. The mathematical model of Tomographic SAR Imaging is deduced and its significance in physics are introduced herein, then the resolution ability in nsr direction is analyzed. At last, the applications of tomographic SAR imaging technology are prospected.
