A Two-Stage SAR Signal Phase Reconstruction Scheme for Multi-temporal InSAR Processing

In recent years, MT-InSAR techniques have gained widespread use in the field of remote sensing. Among these techniques, PS-InSAR is a prominent method. To improve the density and reliability of PS-InSAR products, a two-stage SAR signal phase reconstruction scheme, referred to as TSSPR, is proposed in this paper. The effectiveness of this approach was evaluated by applying it to PALSAR images obtained from February 11, 2007 to February 22, 2011, over Mexico City. The experimental results demonstrate that TSSPR significantly enhances the number and reliability of targets in MT-InSAR applications.
