Educational Note Overview

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.
