【摘要】 采用L波段的PALSAR数据和C波段ASAR数据,以陕西彬长矿区为研究对象,分别从相干性、沉降区域分布等方面进行对比分析,最终发现L波段雷达数据适用于地下开采活动剧烈的活跃期矿区地表监测,C波段雷达数据适用于地下开采初始期及地下开采活动结束后衰落期矿区地表稳定期沉陷监测。更多还原

【Abstract】 By using L-band ALOS / PALSAR data and C-band ENVISAT / ASAR data,taking Shaanxi Binchang mine area as the research object,then compared with the coherence,subside area distribution and other aspects of results. Finally found in underground mining in active period of mine surface monitoringfor L band radar data,C band radar data applies to the ending of underground mining and the initial period of decline in surface stable subsidence monitoring.更多还原
