%X A method of interferometric phase estimation based on the robust beamforming is proposed. The method can provide the accurate interferometric phase estimation, by correcting the spatial steering vector and by taking advantage of the coherence information of the neighboring pixels. Theoretical analysis and experimental results show that the method can present the accurate estimation of the interferometric phase even if the coregistration error be close to one pixel. The effectiveness and robustness of the technique is verified by the simulated and real data.
