The R&S®AREG800A from Rohde & Schwarz is an innovative and versatile solution for testing automotive radar sensors. It can generate dynamic artificial objects with individual distance, object size, radial velocity, and angular direction. The Automotive Radar Echo Generator supports up to 4 GHz of instantaneous bandwidth in all automotive radar bands at 24 GHz and 77 GHz/79 GHz. It has a flexible design that covers all applications from early radar sensor R&D to advanced full vehicle ADAS/AD test cases.
A single R&S®AREG800A connected to an R&S®QAT100 advanced antenna array can generate echoes from up to eight different angular directions and individual objects can be generated from all eight directions simultaneously (one per direction).
This generator allows the minimum object distance to be reduced down to < 4 m with an optional internal analog stepped delay line (e.g., for autonomous emergency braking (AEB) tests). The standard artificial object distances ranging from 17 m to more than 1000 m ensure compatibility with future short-range radar sensors and their applications such as collision avoidance systems.
Multiple R&S®AREG800A and R&S®QAT100 advanced antenna arrays can be synchronized to generate dense scenarios with a large number of individual artificial objects. It allows synchronous parallel over-the-air simulation of multiple automotive radar sensors to test advanced ADAS/AD features involving multiple radar sensors, and sensor data fusion. Up to four conventional mmWave frontends or up to eight R&S®QAT100 advanced antenna arrays can be controlled simultaneously for a simple extension of test capabilities.
The R&S®AREG800A has calibrated IF input and output interfaces to connect further test and measurement equipment for automotive radar measurement tasks (for example, testing of robustness against interfering signals using a connected signal generator, or signal monitoring using a connected signal and spectrum analyzer).
The R&S®AREG800A has an intuitive graphical user interface (GUI) with touchscreen control for manual operation and monitoring of the entire test setup. It has a robust, open real-time interface in line with the open simulation interface (OSI) specification which allows control of the R&S®AREG800A in open-loop and closed-loop test environments. The generator has a field-upgradable design and allows extra features to be added easily by installing software keycodes on site. It has a built-in SCPI macro recorder with a code generator for easy integration into existing test software.
