Interferometric synthetic aperture radar (InSAR) is a powerful remote sensing tool that enhances information acquisition. During InSAR processing, the phase denoising of the interferogram is a mandatory step for topography mapping and deformation monitoring. During the past three decades, a large number of effective algorithms have been developed for efforts related to this topic. In this article, we give a comprehensive overview of InSAR phase-denoising methods, classifying the established and emerging algorithms into four main categories. The purpose is to provide the necessary guidelines and inspiration to related researchers by promoting the architecture development of InSAR signal processing.
