Automotive Radar Echo Generation and Radome Measurements

07 December 2017 - Rohde & Schwarz developed a new range of solutions for automotive radar testing based on its expertise in microwave and millimeterwave testing. The innovative solutions range from analyzing radomes to generating multidimensional automotive radar echo environments. With the advent of advanced driver assistance systems (ADAS), vehicles are increasingly being equipped with radar sensors that support drivers in critical situations.

The new R&S AREG100A automotive radar echo generator was developed for reliable testing of radar sensors in production. The R&S AREG100A supports all automotive radar bands (24 GHz, 76 GHz and 79 GHz). 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 standardized, 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.

Quality automotive radome scanner

Rohde & Schwarz has developed the R&S QAR specifically to characterize 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 localize and identify any material errors or inhomogeneous material that might impact the sensor’s performance. A complete frequency sweep from 75 GHz to 82 GHz is used to measure material attenuation in the 77 GHz and 79 GHz 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.
