A Concept for High Performance Reflector-Based Synthetic Aperture Radar [PDF]
The success of current spaceborne Synthetic Aperture Radar (SAR) is boosting the performance requirement of next generation systems. In order to cope with the evolution of SAR, the design of the new systems will need to meet higher requirements for ...

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