Optimizing D-InSAR processing strategies for time series mining subsidence observation data
In order to extract the dynamic evolution perfectly, by comparing and analysis of advantages and disadvantages of four modes of two pass plus external DEM differential interferometry（2 PASS ＋ External DEM DInSAR） with three pass differential interferometry（3 PASS D-InSAR）. The paper gets the following understanding： As for as D-InSAR surface deformation information extraction and time series analysis, two pass plus external DEM differential interferometry strategy has a fatal flaw but three pass differential interferometry is optimum. Using a interferometry strategy of combination of cumulative phase 3 PASS with adjacent phase 3 PASSe simultaneously, it can improve reliability and the results can be mutual checked.
