| 摘 要： | 干涉灵敏度方程是干涉合成孔径雷达系统优化设计和干涉定标的重要工具。目前的灵敏度方程局限于正侧视干涉几何关系 ,且建立在电磁波波前的平面波模型、地球表面的平地模型基础上。对目前灵敏度方程进行补充和修正 ,扬弃平面波模型和平地模型 ,推导了斜视干涉几何关系下的灵敏度方程 ,并进行了比较分析。

| Abstract: | The interferometric sensitivity equation can be used as an important tool in the interferometric SAR system optimization and interferometric calibration. However, present sensitivity equations are limited to orthorhombic side-glance interferometric geometry based on the wave plane model and the flat earth model. In order to discard these limitations, supplements and modifications to sensitivity equations are presented in this paper, and the sensitivity equations squinted geometry are derived. Finally, a thorough analysis is given. |
