Interferometric filtering is one of the most important procedures in InSAR data processing as it refers to the quality of phase observations and the final products. A variant under the framework of Goldstein filter is presented in this paper, which is based on the robust coherence estimator from the second kind statistics. Compared with the state-of-the-art, the significant advantage of the new method is that more accurate filtering parameter alpha can be deduced and therefore better
more » ... e better performance of the Goldstein filtering can be expected. Experimental results from both simulation and real Envisat ASAR data demonstrate the value of the method.
