摘　　要：为了更好地提取开采沉陷形变的动态演化规律,针对开采沉陷D-InSAR时序差分干涉测量,对比分析了二通加外部DEM和三通差分干涉测量4种模式的优缺点.结果表明,对于D-InSAR地表形变信息提取和时序分析,二通加外部DEM的InSAR干涉策略有致命缺陷,三通法差分较优;得出的采用"累积式"和"相邻重访周期式"相结合的干涉策略,可以提高可靠性,结果可以相互验证,是最优干涉策略.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.
