Popis: Abstract This paper proposes a new interferometric inverse synthetic aperture radar (InISAR) image registration method under squint model based on phase cancellation compensation of combined processing data. Firstly, the residue translational motion component (RTMC) in range profile and the mismatching in the ISAR images induced by joint motion compensation with the same parameters to each antenna are analysed. Then, the RTMC compensation is applied to re‐align the range profile sequences of the received antenna. The phase cancellation compensation is carried out to eliminate the mismatching in the range and azimuth direction, respectively. Simulation results demonstrate that the mismatching between the ISAR images can be compensated effectively, achieving high quality InISAR 3D images consequently.
