Enhancement of SAR Image Resolution with Implementation of Circular GB-SAR System

, 2013
Radars were used for surveillance and remote sensing but nowadays they handle a vast range of applications, radar imagery being one of them. The need for high resolution images was inevitable which lead to Synthetic Aperture Radar (SAR) systems.

A Novel Building Extraction Method for Airborne L-Band CSAR Images Based on Fusion of Scattering Statistical Characteristics

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Circular synthetic aperture radar (CSAR), as a novel imaging mode, enables multiaspect imaging of the same scene, capturing scattering information from different azimuth angles, thereby significantly enhancing the performance of SAR image interpretation.

Applications of Time-Domain Back-Projection SAR Processing in the Airborne Case [PDF]

, 2008
The Back-Projection Algorithm is a SAR processing approach that uses time-domain convolution of the SAR data in order to perform SAR focusing. Some benefits of this approach are exact inversion, ideal motion compensation including topography information ...
