Automotive radar test solution unveiled at EuMW

 

A range of solutions for automotive radar testing based on its expertise in microwave and millimeterwave testing were unveiled by Rohde & Schwarz at European Microwave Week 2017 in Nuremberg. The soon-to-be-available innovative solutions range from analysing radomes to generating multidimensional automotive radar echo environments.

Rohde & Schwarz offered visitors to the exhibition a product preview of the R&S AREG100A automotive radar echo generator for reliable testing of radar sensors in production. The instrument supports all automotive radar bands (24GHz, 76GHz and 79GHz).

Up to three customer-definable fixed radar distances plus an optional Doppler offset for simulation of radial velocity make it a powerful solution for production testing.

Together with the R&S ATS1000 shielded chamber and the R&S QuickStep test execution software, it ensures fail-safe testing of automotive radar sensors.

With this setup, end-of-line testing becomes a standardised, conclusive process to ensure continuous quality control of radar sensors.

Thanks to its small footprint and low weight, the R&S AREG100A can be easily integrated into existing test racks for final inspection of the integrated radar sensor at the OEM’s manufacturing sites.

The R&S QAR has been developed by Rohde & Schwarz to characterise the performance of automotive radar covers such as emblem radomes and car bumpers. The test solution uses an innovative imaging technique that allows very fast measurement of the reflectivity of the DUT.

Car manufacturers can now precisely localise and identify any material errors or inhomogeneous material that might impact the sensor’s performance.

A complete frequency sweep from 75-82GHz is used to measure material attenuation in the 77 and 79GHz automotive radar ranges. With both sets of measurements, the R&S QAR offers the comprehensive and detailed analysis required for future radar generations. The R&S QAR is scheduled to be available in the first quarter of 2018.

Rohde & Schwarz will also demonstrate a breakthrough technology in testing and evaluating radar. The measurement system allows precise angle simulation.
