Millimeter-wave MIMO imaging radar with an ultra-high angular resolution of 0.6 degree

A new cascading multiple input multiple output (MIMO) radar at V-band with 192 virtual elements is developed. The experiment for imaging indoor and outfield is performed with an angular resolution of 0.6°. In addition, sparse array with 108 virtual elements based on this platform is tested with genetic algorithm, the imaging results show that the sparse array imaging with a sparse rate of 55.1% agree well with full array.
