Improved InSAR-BM3D filtering algorithm based on noise variance estimation

Abstract: The conventional InSAR-BM3D filtering algorithm fails to accurately estimate noise variance in regions with low coherence and dense fringe patterns, resulting in inadequate noise suppression ...

Statistical analysis of phase-only correlation functions between two signals with stochastic bivariate phase-spectra

Abstract: This paper proposes statistical analysis of phase-only correlation functions between two signals with stochastic phase-spectra. We derive the expectation and variance of the phase-only ...
