Polarimetric synthetic aperture radar utilized to track oil spills [PDF]
Eos, Transactions American Geophysical Union, 2012 The continued demand for crude oil and related petroleum products along with the resulting upward spiral of the market price of oil have forced oil exploration and production companies to seek out new reserves farther offshore and in deeper waters. The United States is among the top five nations globally in terms of estimated offshore oil reserves and ...

A PolSAR despeckling method based on Wishart gradient and anisotropic diffusion
Electronics Letters, 2021 The anisotropic diffusion filtering is a classical tool in image processing due to its simplicity and effectiveness. In this letter, we propose a new diffusion‐like filter based on the polarimetric synthetic aperture radar (PolSAR) ratio gradients.

Unsupervised Segmentation of Multilook Polarimetric Synthetic Aperture Radar Images [PDF]
IEEE Transactions on Geoscience and Remote Sensing, 2019 This paper proposes a new unsupervised image segmentation method for multilook polarimetric synthetic aperture radar (PolSAR) data. The statistical model for the PolSAR data is considered as a finite mixture of non-Gaussian compound distributions considered as the product of two statistically independent random variates, speckle, and texture.
