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…
