Experimental Study on 3D imaging Using Millimeter-Wave Non-Uniform 2D-MIMO Radar

The main objective in this study is to build a security system without stopping the flow of people at low cost. Most of the existing security systems use SAR (Synthetic Aperture Radar) processing to achieve highly accurate 2D or 3D imaging. However, SAR usually requires long observation time due to mechanical scanning. In this paper, we have developed a high-resolution millimeter-wave MIMO (Multiple-Input Multiple-Output) radar with non-uniform planar arrays for both transmitter and receiver, and evaluated the spatial resolution of the radar by experiments.
