Abstract
Systems and method are provided and include receiving a full calibration matrix for a multiple-input multiple-output (MIMO) radar system having N physical transmit channels, M physical receive channels, and N×M virtual transmit-receive channels, the full calibration matrix being an NM×NM complex matrix previously generated based on chamber measurement data. Transmit and receive calibration matrices are determined based on the full calibration matrix, with the transmit calibration matrix being an N×N complex matrix and the receive calibration matrix being an M×M complex matrix. The MIMO radar system uses the calibration values of the transmit and receive calibration matrices to compensate antenna responses to adjust for physical characteristics of the MIMO radar system while performing at least one of ranging and detection of an object in an environment of the MIMO radar system.
