Pixel selection is a critical procedure in DInSAR processing. In this paper a new temporal phase coherence (TPC) estimation algorithm is proposed for the pixel selection. TPC is calculated based on the estimated interferometric phase noise of all included interferograms. The method has been tested and it turns out to be effective. Comparing with the classical amplitude dispersion (DA) method, TPC method can select more high quality pixels.
