【摘要】 在INSAR处理技术中,相位解模糊非常困难,仍然是影响INSAR应用的一大瓶颈。考虑到优秀的干涉图滤波能使相位解模糊变得容易,提出了一种新的相位解模糊方案首先采用矢量滤波方法对干涉图进行较好效果的滤波处理,然后采用基于相干图(或伪相干图)的区域生长方法进行相位解模糊。实验采用了美国SIR-C数据和欧空局ERS-1/2数据,结果表明干涉图的矢量滤波和基于相干图(或伪相干图)的区域生长方法的综合利用可以成功进行相位解模糊。更多还原

【Abstract】 The phase unwrapping is a big bottleneck of the INSAR applications for its difficulty.Considering that an excellent interferogram filtering can make phase unwrapping easy,it presents a new scheme for phase unwrapping,which includes the vector filtering of interferograms and the region grow phase unwrapping based on the coherence image or on the fake coherence one.The data of SIR-C and of ERS-1/2 were used,whose results show that the application of vector filtering and region grow method can make phase unwrapping successfulty.更多还原
