  • Layover is a nodus in SAR imaging. The unitary ESPRIT algorithm was introduced to resolve the layover problem on the frame of multibaseline InSAR in this paper. The data model of multibaseline InSAR with layover was expatiated firstly, and the layover problem in multibaseline InSAR was boiled down to the estimation of the interferometric phase angle. The basic principle and advantage of the unitary ESPRIT algorithm was depicted, its efficiency was validated by the Monte Carlo simulations. The simulations indicate that unitary ESPRIT algorithm can work well when the looks are very small but the performance of other algorithms degrade sharply.
