Design and Calibration of a Portable 24-GHz 3-D MIMO FMCW Radar with a Non-uniformly Spaced Array and RF Front-End Coexisting on the Same PCB Layer

This paper presents a portable 24-GHz multiple-input multiple-output (MIMO) radar with 16 transmit (Tx) channels and 16 receive (Rx) channels. The radar is intended for short-range localization and three-dimensional (3-D) imaging by detecting the ranges, azimuth angles, and zenith angles of targets...

Summary:This paper presents a portable 24-GHz multiple-input multiple-output (MIMO) radar with 16 transmit (Tx) channels and 16 receive (Rx) channels. The radar is intended for short-range localization and three-dimensional (3-D) imaging by detecting the ranges, azimuth angles, and zenith angles of targets in front of the radar. The radar is capable of two-dimensional (2-D) beamforming achieved using a non-uniformly spaced planar array. A prototype of this 16×16 radar has been built to demonstrate its short-range localization capability.
