| Abstract: | In synthetic aperture radar interferometry(InSAR),the SAR complex image coregistration error is one of the key factors that affect the quality of interferograms.This paper pays attention to the robustness of the novel algorithm,which is based on joint subspace projection,and gives an improved InSAR interferogram estimation method.In order to suppress the interfered elements and advance the accuracy of interferograms,that method weights on the joint correlation matrix.The effectiveness and robustness of the ... |
