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.

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.

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 power ratio that have applications in different areas such as automotive industry and Unmanned Arial Vehicle (UAV) based radar imaging.
