摘要
合成孔径雷达的干涉测量中,高效Goldstein枝切法解缠运行速度快,对内存需求小,但要求干涉相位中只存在少量残点数。为了满足枝切法的需要,干涉预处理中几何校准需采用可控制残点数的插值核。本文综合干涉相位残点数分析与相关性评价,提出了一种基于枝切法的插值核选取方法,并利用ERS-1/2数据验证本文所提出的方法。
In INSAR process, high performance branch-cut detrap method runs fast and needs little momery, but it can endure only a little residues. Because of this, we need a method to keep the residues. This paper uses ERS-1/2 data to test the interpolation kernel in correlation and residues field. We make a conclusion in how to choose the kernel in INSAR resample process.
