雷达差分干涉测量中永久散射体提取方法的对比分析与改进
omparison and Improvement of the Extracting Method of Permanent Scatterers in Differential Interferometric Radar
雷达差分干涉测量中永久散射体的提取是一个重要环节。本文对现有的能够有效提取PS点的方法进行了对比分析，并改进出基于相关系数和相位离差双阈值的提取方法。利用9景ENVISAT的SAR影像进行了实验，通过对实验结果的分析，证明了改进方法的有效性和可靠性。
he extracting of permanent scatterers is an important part in the Differential Interferometric Synthetic Aperture Radar. The paper analyzes the present methods extracting the PS effectively and an improved method based on the correlation coefficient and phase deviation is proposed. Nine scenes of ENVISAT SAR images were used in the experiments. And the effectiveness and reliability of improved method are confirmed by comparing and analyzing the experimental results.
