Automotive MIMO radar for urban environments

A high azimuth and elevation resolution multiple-input-multiple-output(MIMO) radar prototype with 16 Tx and 16 Rx antenna elements was developed in this work to address the autonomous driving vehicle challenges in complex urban environments. This article describes the technological scope of the developed prototype, details the performance challenges and discusses the system design considerations. The main goal of the developed automotive radar prototype is to achieve a high 2D angular resolution in the presence of a large number of radar echoes while maintaining an industry acceptable antenna aperture size and reasonable cost.
