Wavelet-Based Compressed Sensing for SAR Tomography of Forested Areas [PDF]

open access: yes, 2012
Synthetic aperture radar (SAR) tomography is a 3-D imaging modality that is commonly tackled by spectral estimation techniques. Thus, the backscattered power along the cross-range direction can be readily obtained by computing the Fourier spectrum of a ...

Multipath Reflectivity Estimation in Urban Environments for Synthetic Aperture Radar Images [PDF]

open access: yes, 2010
Synthetic Aperture Radar (SAR) images a target region reflectivity function in the multi-dimensional spatial domain of range and cross-range. SAR synthesizes a large aperture radar in order to achieve a finer azimuth resolution than the one provided by ...

A PolSAR despeckling method based on Wishart gradient and anisotropic diffusion

open access: yesElectronics 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]

open access: yesIEEE 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.
