摘    要:采用视向量正交分解方法,在斜视干涉几何关系下,导出了机载干涉SAR目标三维高程重建的解析解,推导了干涉敏感度方程,并进行了详尽的敏感度分析。结果表明,利用导出的敏感度方程可以考察载机姿态测量偏差对干涉三维重建和多普勒频率估计的影响,弥补了目前敏感度分析的不足。

关 键 词:机载合成孔径雷达  敏感度分析  斜视干涉模型  高程重建  数据获取

Abstract:Conventional sensitivity analyses are limited to side-looking interferometric geometry, based on wave plane model and flat earth model. In order to discard these limitations, firstly, under the squinted interferometric geometry, an interferometric three-dimensional height reconstruction model is presented by projecting the unit look vector onto an orthogonal basis. Then, the sensitivity equations are derived. Finally, thorough sensitivity analyses are given. The results of sensitivity analysis show that the influence of aircraft attitude error to 3D reconstruction accuracy and to Doppler frequency estimation can be evaluated by the derived sensitivity equations.
Keywords:Sensitivity analysis  Airborne InSAR  Squinted interferometric model  Height reconstruction
