Most ADAS functions rely on radar sensors, and these safety-critical components must function correctly even under the most demanding of RF environments. A full-vehicles test was conducted to demonstrate the automated ADAS test system, consisting of a radar echo generator, a dynamic target positioning system and an EMS test system. The goal was to prove that simulated scenarios would be effective in activating the VUT ADAS functions and intended responses in an EMC test chamber. This is essential in assessing ADAS functions under electromagnetic interference in EMS testing. This white paper describes this test procedure and contains interesting results.
