摘　　要：基线是形成干涉的基础,同时它的存在又使得干涉SAR系统的相干性降低。本文较全面分析了基线造成的干涉图频谱位移的原因,给出了解决方案,实验表明,经过滤波后,干涉图的相位噪声有较大的减少,并较大提高了干涉图的相关性。Baseline is a base for SAR interferometry. At the same time, it makes the inherent of SAR interferometry reduced. In this paper, the reason of frequency shift of the interferogram is discussed in detail and a solving method is described. The results of computer simulating show that the phase noise of the interferogram is reduced and the inherent is improved greatly.
