Innovative Radar Target Simulation Solution Enhances Autonomous Vehicle Safety Testing

The future of mobility is increasingly being shaped by automated and autonomous vehicles. With the growing adoption of driver assistance systems, one important question arises: How can we ensure the consistent functionality of these ADAS/AD systems and maintain road safety over a vehicle’s lifetime? Ryme Worldwide and Rohde & Schwarz have developed a solution that addresses this challenge. They have introduced a new system that integrates radar target simulation into existing workshop setups, enabling thorough ADAS and AD testing as part of periodic technical inspections (PTI).

Ensuring the long-term functionality of advanced driver assistance systems (ADAS) and autonomous driving (AD) features is essential for vehicle safety and performance. As a result, autonomous vehicle manufacturers must obtain approvals from transport authorities. Moreover, preserving the effectiveness of ADAS/AD over time requires additional safeguards.

Typically, radar target simulators are used in the development and production stages of radar sensors, under highly controlled lab conditions. These simulators tend to be complex, costly, and designed for operation in specialized radio frequency environments. However, Rohde & Schwarz’s breakthrough solution now enables cost-effective, high-quality radar sensor testing in workshop settings for the first time.

For PTI testing, the R&S RadEst radar target simulator can be integrated with Ryme Worldwide’s latest generation of analogue and digital headlight testers, the R-HLT20 and R-HLT30. The headlight tester system, which can easily be moved on rollers, accommodates both test systems on a single column. It is available in both analogue and digital versions, offering users the ability to store and transfer test results via the integrated ASA interface. The headlight tester can be fully adjusted to test various headlight technologies, including H7, Xenon, LED, and Matrix lights. The digital version also features a user-friendly interface, simplifying routine testing procedures, while saving space by combining R&S and Ryme’s systems in the same testing area.

The R&S RadEsT radar target simulator, developed by Rohde & Schwarz, is built to withstand external factors, ensuring reliable performance in workshop conditions. Its ability to deliver precise and repeatable measurements makes it an indispensable tool for real-world assessments. Additionally, the R&S RadEsT includes internal analysis capabilities to measure critical radar sensor quality indicators such as Equivalent Isotropic Radiated Power (EIRP) and occupied bandwidth. Its compact and lightweight design allows for easy integration, all while offering a cost-effective solution.

By collaborating with Ryme Worldwide and utilizing the R&S RadEsT radar target simulator, Rohde & Schwarz has laid the groundwork for incorporating radar sensor testing into future PTIs. This ensures that autonomous driving features remain functional and reliable throughout the vehicle’s lifespan.
