摘要 频谱偏移理论是干涉合成孔径雷达系统特有的一个很重要的问题,它是由基线的存在而导致的干涉合成孔径雷达特有的几何关系造成的。该文首先分析推导了干涉信号频谱偏移理论的成因,并利用所得频谱偏移理论的公式深入分析了其和空间基线去相关、干涉合成孔径雷达系统基线以及干涉合成孔径雷达系统特有平地效应之间的关系,同时采用了在频域去平地效应的方法对实际数据进行仿真、分析,验证所得结论的正确性。 Frequency shift is a distinctive problem in InSAR system which is produced by the unique geometry of the system resulted from the effect of baseline. In this paper,the difference of the incidence angle is uncovered as the key cause of quency shift. The paper also goes deeply into analyzing the relationship between frequency shift and other factors, such as deconelation of baselines, the baseline and the flat earth effect of InSAB system. Simulation results with the SIB-C/X-SAB data show the validity of the conclusion presented in this paper.
