Abstract :
Common used coherence estimator for InSAR gives an approximate estimation, because it prerequisites the SLC SAR image be ergodicity which practically SAR images can not obey. For InSAR, the factors that degrade the usual estimator were discussed, and a new estimator was proposed. Its advantage was shown with simulation and actual data.
