摘要

本文从干涉合成孔径雷达（ＩＮＳＡＲ）的系统原理出发，深入地讨论了影响ＩＮＳＡＲ系统特性的干涉基线．基于形成干涉图像的ＳＡＲ信号之间的频率偏移理论，本文引入干涉合成孔径雷达系统的信号带宽、信噪比及距离向分辨力的概念．根据所提出的概念，得到干涉系统的最优基线，仿真计算结果与实际系统中所采用的系统基线基本吻合．

Abstract

Baseline is the key concept in Interferometric SAR （INSAR） analysis.On the basis of the frequency shift theory between two SAR signals

INSAR signal bandwidth

INSAR signal to noise ratio（SNR） and INSAR range resolution are introduced.In a brief and clear way

the optimum baseline is derived.The simulated results are confirmed with the real parameters.
