Title:
Optimal {Estimation} of {Distributed} {Scatterer} {Phase} {History} {Parameters} from {Meter}-{Resolution} {SAR} {Data} 
Abstract:
Measuring the long-term line-of-sight deformation using a multi pass SAR data stack by standard persistent scatterer technique has been explored since the late 1990s. Researches have been continuously conducted on increasing the data coverage at non-PS rich areas. The recently developed SqueeSAR™ technique has validated the potential of extracting useful information from distributed scatterers. With the availability of high resolution TerraSAR-X spotlight data, this technique can benefit greatly...    »
