[DOI: 10.21982/v18n-hk45] Iterative InSAR Phase Filter
Mestre-Quereda, Alejandro; Lopez-Sanchez, Juan M.; Selva, Jesus; Gonzalez, Pablo
This InSAR Phase filter is based on an iterative method in which the original phase is progressively denoised with adaptive filtering windows of varying sizes. The quality of the filtering is affected by the interferometric coherence, which is related to phase noise. The power spectrum is used to create a smoothing filter for the phase that is based on a Chebyshev interpolation scheme.
