Radar target simulation for validation

Automotive radar object simulation for validation

Advanced automotive radar test system (RTS) from Rohde & Schwarz that includes hardware-in-the-loop (HiL) and vehicle-in-the-loop (ViL)

Homologation and validation of new vehicle models today require millions of test kilometers to be driven under different environmental conditions, on different types of roads in various countries around the world. Due to the increased complexity of automated driving (AD) and advanced driver-assistance systems (ADAS) functions, and new developments in radar technology, testing efforts expand very quickly. Just relying on road testing is no longer practical.

In addition, scenario testing of autonomous driving functions on the public roads can be dangerous, and under conditions that are not easily reproducible. As a result, hardware-in-the-loop (HiL) and vehicle-in-the-loop (ViL) scenario testing of automotive radar is gaining importance.

 ASAM OSI® (Open Simulation Interface)

The standardized ASAM OSI® (Open Simulation Interface) ensures easy integration of the Rohde & Schwarz Radar Target Simulator in any Hardware-in-the-Loop test system. This has been demonstrated together with our partner Vector Informatik using their CANoe and DYNA4 simulation environments.

AVL DRIVINGCUBE™

The small form-factor and fully electronic implementation makes the Rohde & Schwarz Radar Target Simulator the first choice for Vehicle-in-the-Loop testbeds. Developed in a strategic partnership with AVL, you can now perform radar-enabled and GNSS-based testing and validation under safe and reproducible conditions at vehicle level with the AVL DRIVINGCUBE™.

Rohde & Schwarz automotive radar target simulator solution benefits:

  • Less road testing and concurrent testing gives faster time-to-market by speeding up the development cycle
  • Cost reduction by reducing road test kilometers and the number of prototype vehicles with the Rohde & Schwarz automotive radar target simulator
  • Test critical functions such as emergency braking under safe conditions
  • More confidence from using a future-proof test system from leading innovators, able to evolve for future upcoming challenges

Realistic tests on virtual roads

The Rohde & Schwarz radar test system opens a completely new field of possibilities for testing radar-based ADAS and AD features to ensure correct operation in hardware-in-the-loop (HiL) and vehicle-in-the-loop (ViL) testbeds.

Automotive radar object simulation can vary parameters such as distance, angular velocity, size, elevation and azimuth. The scenario testing of changes in angular position becomes possible without physically moving antennas or devices thanks to the innovative antenna array technology. Multiple automotive radar objects can be simulated for all radar-based ADAS features, from emergency braking through cruise control to fully autonomous driving requiring a 360° environment. With an instantaneous bandwidth of 4 GHz ranging from 76-81 GHz, the full frequency range of state-of-the-art and future automotive radar sensors is covered.

Test like it's real

With a responsive real-time interface, controlled by industry-established simulation environments, even challenging, complex and risky automotive radar target generation can be achieved and virtually tested for ADAS in a closed loop.

Future-proof scalability and reliability

Due to an extremely modular and scalable automotive radar object simulation design, all types of vehicles with different amounts and variants of radar sensors can be tested on the same test system and future, unforeseen requirements can be accommodated. Thanks to the innovative system design without mechanically moving antenna parts, the automotive radar target simulator system from Rohde & Schwarz is immune to mechanical wear and tear.
