%X In InSAR data processing,some residual linear phase trend still were left in the flattened interferogram due to the inaccuracy orbit parameters.In order to remove the effects of the residual linear phase trend on final InSAR results,a method to refine the instantaneous frequency estimation of InSAR interferogram and to remove the residual linear trend was introduced.First,the instantaneous frequency of interferogram is estimated with the accuracy of 0.1 fringes with the Chirp-Z transform.Secondly,the linear...
