基于相干目标的InSAR形变提取



   为了克服传统InSAR处理中面临的时间—几何去相干以及大气相位的干扰,选择在时间序列上保持高相干点作为分析对象,利用这这些高相干点集的可靠相位,可以得到这些离散点上的线性形变率和残余高程,并进一步分析得到非线性形变和大气相位的估计。

   To overcome the influence of the temporal and spatial decorrelation, the points are chosen which keep high correlation in time series. And, the estimation of non-linear rate of deformation and atmospheric phase can be derived through detailed analysis.
