In order to better study the details and movement mechanism of crustal deformation,some scholars have actively explored the method of obtaining the accurate three-dimensional deformation field of the crust.In this article,we firstly analyze the necessity of reconstructing 3 D deformation field,and review the development history of the theory about reconstruction of threedimensional deformation field.After introducing the DInSAR technology,several main methods of reconstruction of 3 D deformation fields are described,including the acquisition of three-dimensional deformation field based on the measurement relying on the rise and descending SAR interferometry and azimuth deformation measurement,combining GPS and the deformation values of DInSAR measurements to construct a three-dimensional shape change field,combining observation results about the line of sight alignment with multiple angles of view to construct a three-dimensional shape change field.Each method has its own characteristics and its specific scope of use,this article is about the methods and their characteristics,then on the basis of this,shows the future development of the theoryof 3 D deformation fieldreconstruction.
