Rohde & Schwarz has partnered with Vector Informatik to conduct closed-loop scenario testing of automotive radar sensors for advanced driver assistance systems (ADAS) and autonomous driving (AD). The test combines Vector’s DYNA4 virtual driving simulation platform with Rohde & Schwarz’s latest radar dynamic target simulation system to provide robust validation of key ADAS safety functions, including emergency control in an integrated hardware-in-the-loop (HiL) environment. move.
The R&S AREG800A opens the door to a new world for testing radar-supported ADAS functions.
HiL test technology is primarily used to accelerate the development of complex real-time embedded systems such as ADAS when fully assembled vehicles are not available or are too costly, time-consuming and dangerous. The operation and behavior of its support system is electronically simulated.

System configuration includes Vector DYNA4 virtual driving software and Rohde & Schwarz radar test system. Vector DYNA4 virtual driving software provides environment simulation and user interface for scenario configuration and test execution. Rohde & Schwarz radar test system is based on DYNA4 environment The list of ASAM OSI objects implemented in the simulation software generates dynamic targets for the radar sensor under test. When the radar detects an object, Vector CANoe receives the bus output signal of the radar sensor and the target detected by the radar, and then uses the software to analyze and visualize them. Detected objects are also compared to the simulated ground truth.

The Rohde & Schwarz radar test system consists of the R&S AREG800A automotive radar target simulator as the digital backend and the R&S QAT100 advanced antenna array as the frontend. This solution opens the door to a new world for testing the ADAS capabilities of radars and ensures the safety of autonomous driving functions in HiL settings. Innovative antenna array technology allows complex targets to be generated for radar sensors with variable range, radial velocity, target size and angular orientation. The antenna and test equipment do not need to be physically moved. A responsive and dedicated HiL interface compliant with the ASAM Open Simulation Interface specification allows realistic over-the-air simulation of radar sensors for challenging, complex and even dangerous driving scenarios. The radar test system is future-proof and supports modularity and series production. In addition to providing standard radar-based testing of ADAS functions such as adaptive cruise control (ACC) and automatic emergency braking (AEB) scenarios, the system can be easily upgraded to cover advanced test cases. It can be enhanced for the complexity of future scenarios to meet different needs – which is especially critical for autonomous driving.
The combination of high-reduction simulation software and air-to-air radar target simulation system is an important advance. This combination accelerates the development of ADAS functions and enables users to reliably and realistically test ADAS/AD functions and master complex verification processes in a fully controlled and representative environment.
