Radar target simulation for validation

Radar target simulation for validation

Most complete and capable automotive radar test system available

Homologation and validation of new vehicle models today require millions of test kilometers to be driven in various 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) and development of radar technology, testing efforts grow very quickly and pure road testing is not practical any more.

In addition, testing autonomous driving functions on the public roads can be dangerous and is not reproducible. Therefore Hardware- and Vehicle-in-the-Loop testing of automotive radar is gaining importance.

Your challenges:

  • End-to-end verification, validation, calibration or homologation of AD/ADAS functions at component and full vehicle level
  • Reproducing complex traffic scenarios, stimulating radar sensors over-the-air
  • Ensuring test equipment for radar sensor over-the-air stimulation should be scalable in size and technical specifications to cover the increasing number of targets and future complex scenarios
  • Meeting the increased testing complexity requirement whilst minimizing cost and accelerating time-to-market

Test solution features

  • Radar test cases and driving scenarios can be easily defined and executed with highest reproducibility
  • Complex radar object scenarios including multiple sensors can be simulated over-the-air
  • Increased accuracy and repeatability from fully-electronic antenna array
  • Fully scalable covering all use cases from R&D to production, easily upgradable to cover future requirements

Test solution benefits

  • Less road testing and concurrent testing gives faster time-to-market by speeding up development cycle
  • Cost reduction by reducing road test kilometers and the number of prototype vehicles
  • 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 to upcoming challenges
ADAS in a closed loop
With a responsive real-time interface, controlled by industry-established simulation environment, even challenging, complex and risky driving scenarios can be generated and virtually tested for ADAS in a closed loop.

Realistic tests on virtual roads

Test today’s and tomorrow’s radar based ADAS

The Rohde & Schwarz radar test system opens a completely new field of possibilities for testing radar-based ADAS and AD features and including ensuring their correct operation in Hardware- (HiL) and Vehicle-in-the-Loop (ViL) testbeds.

Objects can be emulated with variable distance, angular velocity, size, elevation and azimuth. The simulation of angular position becomes possible without physically moving antennas or devices thanks to innovative antenna array technology. Multiple objects can be emulated for all radar-based ADAS features, from emergency braking through highway pilot 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 driving scenarios can be generated and virtually tested for ADAS in a closed loop.

Future-Proof Scalability & Reliability

Due to an extremely modular and scalable 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 test system is robust and immune to mechanical wear-out.

The Rohde & Schwarz enabled radar test system for AVL DRIVINGCUBE™ ViL testbeds

Reproducing realistic road testing in the lab requires a very complex test system. Therefore, two leading companies, Rohde & Schwarz for high frequency testing of radar, GNSS and V2x and AVL, the world’s largest independent company for the development, simulation and testing of powertrain systems and pioneer in the field of innovative solutions, join forces in a strategic partnership to develop a game-changing new ViL radar test system as part of AVL DRIVINGCUBE™ for bringing road testing into the lab.
