Most of the modern cars are equipped with au-tomotive radar sensors. These are important components of advanced driver assistance systems (ADAS). Over-the-air (OTA) stimulation of the radar sensor can be used to realize testing of such systems on a test-rig for ready-to-drive cars; many radar target stimulators (RTS) enable OTA testing. Most state-of-the-art RTS are only capable of generating point targets. Unlike point ones, the real radar targets look more like target clouds. In this paper we discuss a novel concept to create more realistic synthetic radar targets with reasonable effort utilizing RTS.
