3D Near-Field Virtual MIMO-SAR Imaging using FMCW Radar Systems at 77 GHz

no code implementations30 Aug 2022 Shahrokh Hamidi

In this paper, we present 3D high resolution radar imaging at millimeter-Wave (mmWave) frequencies via a combination of virtual Multiple Input Multiple Output (MIMO) Frequency Modulated Continuous Wave (FMCW) Radars with Synthetic Aperture Radar (SAR) which results in a low cost and high speed 3D mmWave imagery system with low complexity.

Millimeter-Wave Circular Synthetic Aperture Radar Imaging

no code implementations22 Dec 2020 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 Circular Synthetic Aperture Radar (CSAR) technique.

3D Near-Field Millimeter-Wave Synthetic Aperture Radar Imaging

no code implementations1 Nov 2020 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.

Single Channel MMWave FMCW Radar for 2D Target Localization

no code implementations30 Oct 2020 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.

Sparse Based Super Resolution Multilayer Ultrasonic Array Imaging

no code implementations30 Jul 2020 Shahrokh Hamidi

Relying on the fact that the image of interest is sparse, we cast such an array based imaging problem as a sparse signal recovery problem and develop two types of imaging methods, one method uses only one transducer to illuminate the region of interest {and for this case the system is modeled as a single input multiple output (SIMO) system.
