Automotive radar interference testing

Ensure the correct operation of automotive radar sensors in safety-critical applications

Automotive radar sensors are used in complex and safety-critical applications such as advanced driver-assistance systems (ADAS) and autonomous driving (AD). That all sensors function correctly and in compliance with relevant regulations, both under nominal and adverse conditions, must be verified. There are also liability considerations for original equipment manufacturers (OEMs) and radar-module suppliers, so 100% reliable automotive radar compliance testing based on trustworthy instruments is required to minimize risk and ensure an efficient approval and certification process.

Rohde & Schwarz is engaged globally with manufacturers and standardization bodies to proactively develop leading-edge solutions for automotive radar compliance testing that OEMs, Tier 1 suppliers and relevant test houses can all rely on.
