| 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．

| Abstract: | 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 D-InSAR) 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 PASS’ simultaneously,it can improve reliability and the results can be mutual checked. |
