摘要
An apparatus and method for stacking multi-temporal MAI interferograms Disclosed are disclosed herein. The apparatus includes a processor configured to: generate a forward-looking InSAR (Interferometric Synthetic Aperture Radar) interferogram and a backward-looking InSAR interferogram of multi-temporal interferometric pairs; generate a residual forward-looking interferogram and a residual backward-looking interferogram by removing low-frequency phase components from the forward-looking InSAR interferogram and the backward-looking InSAR interferogram; generate a stacked forward-looking interferogram and a stacked backward-looking interferogram by separately stacking the residual forward-looking interferogram and the residual backward-looking interferogram; and generate a stacked MAI interferogram based on a phase difference between the stacked forward-looking interferogram and the stacked backward-looking interferogram.
