High Angle Resolution Automotive Radar Based on Simultaneous 12Tx Doppler-Multiplex MIMO

To enhance the angular resolution of automotive radar sensors, multiple-input multiple-output modulation schemes are used. In this paper, a simultaneous transmission of 12 orthogonal waveforms in a 12Tx/16Rx antenna array, within a Doppler-Multiplex, is deployed. The resulting 192 simultaneous MIMO channels allow a high angle resolution capability. The concept is presented and demonstrated using an evaluation platform.
