Summary:
Testing of automotive radar systems is mandatory to provide high safety standards in automated and autonomous driving systems. Full vehicle tests with a ready to drive car are often carried out on automotive dyno test rigs. To test the radar sensor within the whole system a radar target stimulator can be used to save space and ensure reproducibility of the tests. However, over the air stimulation is sensitive to the industrial environment on such automotive test rig. Reflections and scattering on metal surfaces cause clutter and undesired ghost targets. To guarantee reliable tests on these test rigs, a suitable absorber concept has to be developed to suppress these reflections. To achieve this, the environment at an automotive test rig was analysed and the demands on absorbers were identified. Based on this information, a measurement for comprehensive absorber characterisation was designed, allowing to find an absorber that fulfils the demands of this application.
