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…
High Resolution Millimeter Wave Imaging Based on FMCW Radar Systems at W-Band
Shahrokh Hamidi, M. R. Nezhad-Ahmadi
In this paper, we present a unique high resolution, compact, low-cost, lightweight, and highly accurate millimeter wave imagery system capable of operating in all weat…
Entropy-Based Doppler Centroid Estimation and Speckle Noise Reduction for Spaceborne SAR Imaging
Shahrokh Hamidi
In this paper, we present strip-map mode spaceborne Synthetic Aperture Radar (SAR) imaging with the focus on Doppler centroid frequency estimation. The non-zero Doppler centroid fr…
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…
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…
