Modeling and Analysis of Spatial and Temporal Land Clutter Statistics in SAR Imaging Based on MSTAR Data
Shahrokh Hamidi
The statistical analysis of land clutter for Synthetic Aperture Radar (SAR) imaging has become an increasingly important subject for research and investigation. It is also absolute…
Target Detection in Sea Clutter with Application to Spaceborne SAR Imaging
Shahrokh Hamidi
In this paper, the challenging task of target detection in sea clutter is addressed. We analyze the statistical properties of the signals which have been received from the scene an…
Joint Image De-noising and Enhancement for Satellite-Based SAR
Shahrokh Hamidi
The reconstructed images from the Synthetic Aperture Radar (SAR) data suffer from multiplicative noise as well as low contrast level. These two factors impact the quality of the SA…
