星载InSAR最佳基线的估计

Estimation of Optimal Baseline in the Spaceborne InSAR

基线是干涉合成孔径雷达(InSAR)中的重要参数,在InSAR的系统设计、数据处理、误差分析中起着非常重要的作用.本文从测高误差出发,导出了最佳基线的一个表达式,并进行了计算机仿真,仿真结果与实际系统中所采用的基线基本吻合.

The baseline is an important parameter in InSAR ,and it is crucial in InSAR system design, data pro-cessing and error analysis. In this paper, an expression of the optimal baseline is derived from height finding error. And computer simulation is used to testify the correction of analysis. The simulated results confirms to real parame-ters.
