As vehicles integrate more ADAS & Automated Driving (AD) functions, precise radar validation is essential for safety features like AEBSS and SAE Level 2 & 3 automation. Simulation-based testing offers flexibility but lacks real-world accuracy, while road testing is costly and inconsistent. Hardware-in-the-Loop (HIL) solutions bridge this gap, enabling real-time radar sensor evaluation with high repeatability.Rohde & Schwarz supports this with the R&S®AREG800A radar echo generator and R&S®QAT100 antenna array, simulating dynamic targets in angle, range, velocity, and size, and integrating via Open Simulation Interface (OSI). With cutting-edge radar test solutions, R&S ensures safer, more reliable ADAS/AD systems.This educational note explores the current state of closed-loop testing for radar-based hardware, focusing on how Hardware-in-the-Loop (HIL) systems enable realistic validation of automotive radar sensors. It highlights key driving scenarios that HIL must address and demonstrates how the R&S®AREG800A radar echo generator and R&S®QAT100 antenna array support closed-loop validation.

Automotive radars are essential to safety systems such as collision avoidance and adaptive cruise control. The radars are a pillar of ADAS/AD systems and an important part of sensor fusion. The effective isotropic radiated power (EIRP) of automotive radar sensors is the total power emitted from radar antennas and a comprehensive measure of signal strength and coverage capability (essential to assessing automotive radar sensor performance). The AREG800A automotive radar echo generator makes for easy EIRP measurements when validating automotive radar sensors.

Automotive radar is vital to the advanced driver assistance systems (ADAS) that will help achieve Net Zero (zero accidents, zero fatalities) targets in the automobile industry. In a driving environment, radar sensors must detect real objects even when there is interference. The R&S®AREG800A automotive radar echo generator is essential to any solution that tests radar sensor immunity to interference.
