AN ALGORITHM FOR INTERFEROMETRIC SAR DATA PROCESSING
-
摘要: 本文提出了干涉合成孔径雷达(INSAR)从SAR单视复图像到非模糊相位图的一种实用数据处理方法。详细讨论了其中的去平地相位、相位图噪声抑制、相位展开等的实现方法。并用ERS-1/2的真实SAR图像数据验证该方法的有效性。Abstract: In this paper, an algorithm of generating INSAR unwrapped phase image from SAR single-look complex images is presented. Besides the general processing technique, this article focuses on the methods of flat-earth phase removal, phase noise reduction and phase unwrapping. The availability is tested by the results of processing ERS-1/2 SAR images.
