Abstract
Land subsidence is a phenomenon that causes the consolidation and compression of the surface soil of the earth's crust due to various complex natural and man-made factors,and then causes regional surface displacement.In order to solve the problem that land subsidence monitoring by current technology is easily affected by various factors such as temporal and spatial decoherence,atmospheric delay,etc.,which leads to the inability to obtain reliable deformation information,taking Wuhan City,where surface deformation phenomena are more serious,as the research area,PS-InSAR(Persistent Scatters for SAR Interferometry)technology is proposed,which can not only improve the spatio-temporal resolution and unwrapping accuracy of deformation monitoring,but also reduce the impact of temporal and spatial decoherence,and at the same time reduce the error caused by atmospheric delay.It is a comprehensive acquisition of land subsidence monitoring information.关键词
