Abstract：There exist a lot of phase noises in interferogram, which will adversely affect the product precision of interferometric synthetic aperture radar (INSAR). It is therefore very important to reduce the phase noise before phase unwrapping. In this paper, the authors deal with four noise filtering methods, namely multi-look processing, medium filtering, gradient-based adaptive filtering and additive filtering. In practice, the combination of these filtering methods would yield even better result.
