In this paper, a multitemporal SAR image despeckling based on non-local theory (NLG-MulSAR) algorithm is proposed, which improved the basic framework of ratio-based denoising (RABASAR). The temporal and spatial information integrated. super ratio acquisition part RABASAR are optimized by NLG filtering algorithm. does not need to transform multiplicative noise into additive synthetic aperture ra...

A polarimetric synthetic aperture radar (PolSAR) sensor is able to collect images in different polarization states, making it a rich source of information for target characterization. PolSAR are inherently affected by speckle. Therefore, before deriving ad hoc products from the data, covariance...
