A novel approach for a MIMO FMCW radar system with frequency steered antennas for 3D target localization

In this paper, a new approach for a MIMO FMCW radar system with direction of arrival estimation capabilities in azimuth and elevation direction is presented. This is achieved using an equally spaced linear virtual antenna array with frequency steered transmit antennas and frequency selective signal processing. The system and antenna concepts together with the necessary signal processing are presented and then evaluated based on a simulated scenario.
