The R&S®AREG800A is a powerful automotive radar echo generator. It is capable of over the air stimulation of automotive radar sensors with multiple static or dynamic radar objects. It can either be paired with R&S®AREG8 mmWave frontends for RF performance testing, or with the R&S®QAT100 antenna array for simulating ADAS scenarios. This application note shows how to configure the R&S®AREG800A with either R&S®AREG8-24/81 remote millimeter wave frontends or the R&S®QAT100 advanced antenna array. It covers the instrument setup, connections, and configuration necessary to perform static object simulation using a basic setup.

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.
