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

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

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. We develop an algorithm to reconstruct the image from the raw data and analyse different aspects of the system analytically. Furthermore, we discuss the differences between the proposed systems in the literature and the one presented in this work. Finally, we apply the proposed approach to the experimental data collected from a single channel FMCW radar operating at $\rm 79 \;GHz$ and present the results.
