基于ALOS PALSAR数据进行雷达差分干涉提取玉树地震同震地表形变场
|
摘要
本文针对2010年4月14日玉树地震引起的地表形变,使用日本ALOS卫星PALSAR L波段雷达影像数据,应用两轨雷达差分干涉(DInSAR)处理得到了以玉树为中心11 000km2范围内的同震形变场,空间分辨率为8m,并在此基础上对玉树地震的震源机制和发震机理进行了分析。研究结果表明L波段雷达数据适合在地形起伏较大的地区进行DInSAR形变探测。该同震形变场信息可为玉树地震的同震形变反演提供参考数据。该研究进一步证实DInSAR技术在大规模地表形变探测和地学研究领域具有广阔的应用前景。
Based on PALSAR L-band SAR data of ALOS satellite,two-pass differential interferometric synthetic aperture radar(DInSAR) method were applied for analyzing the ground displacement due to the Yushu earthquake shock in the paper.It obtained the coseismic deformation field with spatial resolution of 8m in an area of about 11000km2,and analyzed the distribution and characteristics of the displacement.The research indicated that L-band SAR data is excellent for monitoring coseismic deformation in complex terrain or vegetation areas.Moreover,the high-resolution coseismic deformation field could provide useful data for the inversion of source parameters and the analysis of mechanism of the earthquake.It proved that DInSAR technique has great potential to be used in deformation detecting of large area or research of geology.
