Analysis of Scattering Center Model for High Resolution SAR Targets
Author(s): 
Pages: 416-424
Year: Issue:  6
Journal: Radar Science and Technology

Keyword:  合成孔径雷达高分辨合成孔径雷达SAR图像解译散射中心;
Abstract: 散射中心是光学区雷达目标电磁散射的基本特征,是高分辨SAR图像解译的根本特征.以高分辨SAR图像解译为应用背景,分析了目前典型的三种散射中心模型(理想点散射中心模型、衰减指数和模型、属性散射中心模型)的优缺点和适用条件,并导出了模型及模型参数间的关系.通过理论分析、仿真及实测SAR图像数据验证了属性散射中心模型是目前最符合高分辨SAR图像解译应用需求的散射中心模型.在此基础上,分析了属性散射中心的...
