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 requires 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 modularity of Automated Driving (AD) and Advanced Driver-Assistance Systems (ADAS) and the increased quantity and complexity of functions of upcoming vehicles, testing efforts grow very quickly and pure road testing is no longer practical.

In addition, testing autonomous driving functions on public roads can be dangerous and is not reproducible. Rohde & Schwarz together with automotive engineering services provider AVL provide a game changing solution for testing radar-enabled ADAS and AD functions on Vehicle-in-the-Loop test beds, bringing the road into the lab.

Your challenges

  • End-to-end verification, validation, calibration or homologation of ADAS functions at full vehicle level
  • Reproducing complex traffic scenarios on a Vehicle-in-the-Loop testbed, stimulating radar sensors over-the-air
  • Test equipment for radar sensor over-the-air stimulation should be scalable to the higher number of targets required in modern vehicles and needs sufficient performance for complex scenarios
  • Meeting the increased testing complexity requirement whilst minimizing timescales and cost

Benefits of Rohde & Schwarz solutions

  • ADAS test cases and driving scenarios can be defined and executed with highest reproducibility
  • Less road testing and parallel testing gives faster time-to-market by speeding up development cycle
  • Complex radar object scenarios including multiple sensors can be simulated over-the-air
  • Cost reduction by reducing road test kilometers and the number of prototype vehicles
  • Test critical functions such as emergency braking under safe conditions
  • Confidence from using a future-proof test system from leading innovators, able to evolve to upcoming challenges

The Rohde & Schwarz enabled AVL DRIVINGCUBE™ radar test system

Test today’s and tomorrow’s radar based ADAS

The Rohde & Schwarz enabled radar test system as part of AVL DRIVINGCUBE™ opens a complete new field of possibilities for testing radar-based ADAS and AD features and ensuring their correct operation of Vehicle-in-the-Loop (ViL) test beds.

Objects can be emulated with variable distance, 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.

Automotive Target Simulation
Test like it's real

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.

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 resistant to mechanical wear-out.

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 for provision of advanced simulation software, vehicles on a dynometer and complete test beds, join forces in a strategic partnership to develop a game-changing new system for bringing road testing into the lab.
