Abstract A rigorous model extracting the 3D dimension deformation field by integrating the multiple aperture interferometry (MAI）data and the conventional InSAR data along both ascending and descending orbits for was proposed in the paper.The coseismic deformation field caused by the 2003 Bam earthquake (Iran）was selected as the testing site，and the 3D deformation field derived with the model is compared with the existing fault model and the azimuth offsets (AZO）derived by coregistration of amplitude images.The testing results indicate that the azimuth displacement derived by MAI is improved in terms of accuracy and computation efficiency，and the 3D coseismic displacement is consistent with the fault model.The root mean square error (RMSE）between the two types of results are 2.7，4.1 and 3.2 cm in vertical，northsouth and eastwest direction，respectively.
