Millimeter-Wave Circular Synthetic Aperture Radar Imaging
Shahrokh Hamidi, Safieddin Safavi-Naeini
In this paper, we present a high resolution microwave imaging technique using a compact and low cost single channel Frequency Modulated Continuous Wave (FMCW) radar based on Circul…
3D Near-Field Millimeter-Wave Synthetic Aperture Radar Imaging
Shahrokh Hamidi, Safieddin Safavi-Naeini
In this paper, we present 3D high resolution radar imaging process at millimeter-Wave (mmWave) frequencies by creating the effect of a large aperture synthetically. We use a low co…
Single Channel MMWave FMCW Radar for 2D Target Localization
Shahrokh Hamidi, Safieddin Safavi-Naeini
In this paper, we present a 2D target localization method using two low cost and compact Mellimeter Wave Frequency Modulated Continuous Wave (MMW-FMCW) radars. To create a 2D map w…
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…
Sparse Based Super Resolution Multilayer Ultrasonic Array Imaging
Shahrokh Hamidi
In this paper, we model the signal propagation effect in ultrasonic imaging using Huygens principle and use this model to develop sparse signal representation based imaging techniq…
CDM Based Virtual FMCW MIMO Radar Imaging at 79GHz
Shahrokh Hamidi, Safieddin Safavi-Naeini
Multiple Input Multiple Output (MIMO) Frequency Modulated Continuous Wave (FMCW) radars operating at 79GHz are compact, light and cost effective devices with low peak-to-average po…
