Urban Target Monitoring Using High Resolution SAR Data
城市目标高分辨率SAR遥感监测技术研究进展

High-resolution Synthetic Aperture Radar (SAR) satellites will provide valuable data for urban area monitoring and promote the identification of urban targets greatly,because targets take on multi-dimension characteristics in high\|resolution SAR images.Nevertheless,urban targets become very complicated in high-resolution SAR images due to the spatial complexity of urban targets,multi-bounce scattering between adjacent targets,as well as the inherent geometric distortions and speckle noises of SAR imaging.In this paper,literature was reviewed surrounding electromagnetic scattering and SAR imaging mechanisms,fine structure extraction and 3D reconstruction of urban targets,and future research focus of this domain was analyzed.
