Achieving high-resolution 2-dimentional (2D) or 3-dimentional (3D) imaging with millimeter-wave radar requires a large number of antenna elements. Synthetic aperture radar (SAR) is commonly used to achieve high-resolution imaging. However, SAR usually requires long observation time due to mechanical scanning. In this study, we have developed a prototype high-resolution millimeter-wave MIMO (Multiple-Input Multiple-Output) radar with non-uniform planar arrays for both transmitter and receiver. We achieved high-resolution 3D imaging by applying virtual array processing to the received data. In this report, we provide the spatial resolution evaluation of the prototype millimeter-wave non-uniform 2D-MIMO radar by experiments.
