Interferometric features of land surface from a series of JERS-1 SAR interferograms

Experiments for differential interferometry were conducted over sixteen months using corner reflectors (CRs). From eleven scenes acquired during the period, four high-quality interferograms are produced. Using CRs as ground reference points, baselines are estimated. Referring to the digital elevation model (DEM), topographic effects are removed. Interferometric features (coherency and differential phase) are analyzed for typical land surface types; i.e. forest, urban, residential, paddy and farm
