A multi‐temporal InSAR method incorporating both persistent scatterer and small baseline approaches

Synthetic aperture radar (SAR) interferometry is a technique that provides high‐resolution measurements of the ground displacement associated with many geophysical processes. Advanced techniques involving the simultaneous processing of multiple SAR acquisitions in time increase the number of locations where a deformation signal can be extracted and reduce associated error. Currently there are two broad categories of algorithms for processing multiple acquisitions, persistent scatterer and small baseline methods, which are optimized for different models of scattering. However, the scattering characteristics of real terrains usually lay between these two end‐member models. I present here a new method that…
