77 GHz lens-based multistatic MIMO radar with colocated antennas for automotive applications

With the fast development of highly integrated 77 GHz SiGe-MMICs, cost effective and reliable radar systems are feasible to significantly increase driving safety in all vehicle classes. New features have to be implemented in these sensors to fulfill the ascending requirements for future systems. Important demands will be the detection and separation of multiple targets in a range cell and the exact measurement of angles in azimuth and elevation. In this paper we present a new lens based 77 GHz MIMO radar system with SiGe MMICs. The center of attention in our investigations is the comparison between conventional lens based radar configurations and lens based MIMO radar configurations.
