High-precision test chamber for developing automotive radar
The ATS1500C from Rohde & Schwarz is a test chamber for high performance automotive radar testing, offering an outstanding indirect far-field testing performance.

Automotive radar is one of the key technologies that drives progress in the advanced driver assistance systems (ADAS) needed for future generations of driverless vehicles. At Productronica 2019 in Munich, Rohde & Schwarz provided an early preview of its latest system for testing state-of-the-art, next generation automotive radar sensors. The test system consists of the new, compact ATS1500C automotive radar test chamber for far-field testing, in combination with the AREG100A automotive radar echo generator for precise radar target simulation at various distances. Together, they form a unique and innovative indirect far-field testing system for reliable and reproducible verification of radar sensors throughout the R&D and validation phase in a user-friendly and extremely compact lab setup. The test setup enabled the precise calibration and verification of Uhnder's new, fully integrated 4D digitally modulated automotive radar-on-chip (RoC).

The ATS1500C features a high accurate compact antenna test range (CATR) reflector, generating a 30 cm diameter quiet zone for testing in the frequency range from 77 81 GHz. Its high-precision 3D tilt-tilt positioner permits testing of premium automotive radars. A carefully designed absorber layout eliminates ghost targets during simulation.
