SAAS-Net: Self-supervised Sparse SAR Imaging Network with Azimuth Ambiguity Suppression

The traditional synthetic aperture radar (SAR) imaging algorithm typically demands substantial computational resources due to its involvement in large-scale matrix operations, which presents challenges for imaging in expansive scenes. By leveraging the reversibility of the imaging process, a method that simulates the inverse process of generating ...

On the use of full polarimetric SAR data to remove azimuth ambiguity: Application ship detection

, 2014
In the framework of Maritime Security and Safety, Synthetic Aperture Radar (SAR) ship detection is nowadays crucial. Nevertheless, automatic SAR ship detection is not an easy task due to the speckle and SAR artifacts that may cause false alarms. Although
