The topic of autonomous driving currently draws much media attention, and automobile manufacturers and component suppliers are working on the realisation of autonomous vehicles. On the way to a fully autonomously driving vehicle, different levels of au- tomated driving have to be mastered as depicted in Tab. 1 and defined, for example, by [1]. With an increasing automation level, the execution, monitoring, and fallback performance are increasingly handled by the system and not by the human

In contrast to video cameras and laser scanners, a radar sensor is nearly independent of severe weather and light conditions and even remains operational in complete darkness and snowfall. By exploiting the reflections of the electromagnetic waves between road surfaces and the underbody of vehicles it is even possible to detect hidden targets behind other vehicles.
