利用SBAS-DInSAR技术提取腾冲火山区形变时间序列
TIME SERIES OF DEFORMATION IN TENGCHONG VOLCANIC AREA EXTRACTED BY SBAS-DInSAR
摘要
Abstract
On the basis of the 6 JERS-1 SAR images, the time series of deformation in Tengchong volcanic are-a were obtained by SBAS-DInSAR technique through separating the linear deformation phase, the nonlinear deformation phase, the atmospheric phase screen and the DEM residual error phase. Compared with the GPS measurement results, SBAS-DInSAR technique can detect the crustal deformation at the precision of sub-cm level. The deformation of the Danzha-Gaotian fault is obviously different between the two sides, which may relate the chamber below. The deformation pattern of the Dayingshan area indicates that there is probably an buried fault underground.关键词
