HIL Test Bench for Over-the-Air Radar-in-the-Loop Simulation

• HIL system with Automotive Simulation Models (ASM) to simulate the vehicle and traffic environment, and to control the dSPACE Automotive Radar Test System (DARTS)
• Over-the-air stimulation of the radar sensor front end to test the complete chain of effects
• Testing the radar ECU with all software and hardware layers in the original mounting position

Aside from cameras, radar sensors are the most important sensors in advanced driver assistance systems (ADAS). They are essential in the chain of effects of an ADAS function. Therefore, reliable test methods are necessary. Over-the-air radar-in-the-loop simulation allows test engineers to validate the complete chain of effects including the sensor’s radio frequency (RF) components in the laboratory.
