New Rohde & Schwarz test system for automotive radar sensors electronically simulates even laterally moving objects

The new R&S RTS radar test system from Rohde & Schwarz simulates driving scenarios for testing radar based advanced driver assistance systems (ADAS) and radar sensors used in autonomously driving cars (AD) entirely over the air. The test solution consists of the new R&S AREG800A automotive radar echo generator as a backend and the R&S QAT100 antenna array as a frontend. Laterally moving objects, i.e. objects approaching from the side, are currently simulated by mechanically moving antennas. The R&S RTS replaces the mechanical movement by electronically switching individual antennas in the frontend on and off. Even objects moving laterally to the car at very high speed can be simulated reliably and reproducibly. The R&S RTS is able to simulate the radial velocity (Doppler shift) and the size (radar cross section) of objects at user configurable – including very small – ranges. Countless objects can be represented by cascading multiple R&S AREG800A backends. The R&S RTS moves tests currently performed on the road to the lab. This allows early error detection and a significant reduction in costs.

Rohde & Schwarz presents its comprehensive solutions for 5G NR device testing at MWC21 in Barcelona

For cellular device manufacturers, 5G NR means a new complexity with a high impact on the development process. Advanced RF interfaces with antenna arrays operating in the mmWave range are making test setups and procedures more challenging. With Mobile World Congress returning to Barcelona in June 2021, Rohde & Schwarz is showcasing the latest highlights of its cellular device testing portfolio, which cover all stages from early 5G NR device design phases to conformance testing to device manufacturing.
