摘要

•A method to determine weight matrix for InSAR 3-D deformation resolving is proposed.•Using high-precision GPS observation to evaluate the accuracy of multi-LOS D-InSAR.•A combined fitting model associated with the position and elevation is built.•Reasonable determination of weight matrix increases accuracy of the 3-D deformation.
