TDM FMCW MIMO Radar for Imaging and Change Detection

Imaging radar can achieve continuous monitoring of the area, and will not be affected by the weather conditions. Therefore, it has been widely used in security and environmental monitoring. Compared with the traditional single-input-multiple-output (SIMO) radar, multiple-input-multiple-output (MIMO) radar has a larger virtual antenna array, which helps to improve the radar's angular resolution. This paper proposed an X-band time division multiplexing (TDM) frequency modulated continuous wave (FMCW) MIMO radar, and the experimental results are presented, including the results of imaging and change detection.
