| 摘 要： | 收集了2008年12月至2009年7月的6景覆盖济宁某矿区ENVISATASAR数据，利用差分干涉测量技术进行矿区地面沉降监测应用研究。通过“双轨法”和“三轨法”，进行差分干涉处理，提取了差分干涉图、增强干涉图、相干图和地面形变图。并且对测量处理结果进行了分析和讨论，从而验证了差分干涉测量技术在矿区地面沉降监测中应用的可行性。

| Abstract: | In this paper,six views coverage of Jining mining ENVISAT ASAR data from December 2008 to July 2009, were collected, and differential interferometry is used to moni- tor mine subsidence. Extraction of lhe differential interferogram, enhanced interferogram, coherence map and ground deformation map were acquired by the two-track method and the three-track method differential interferometric processing respectively. The analysis for them verifies feasibility of application for the differential interferometry to monitor land subsidence in mining area. |
