Radar is the key technology for the development of advanced driver assistance systems (ADAS), able to instantaneously measure distance, angle and velocity and produce detailed images of the surroundings. It enables safety-critical features such as emergency braking and therefore chipsets, sensors and modules need to be tested thoroughly at each phase from development and conformance to production. Test products, software and OTA systems from Rohde & Schwarz assist component suppliers and vehicle manufacturers to develop robust and high-performance automotive radar, able to function correctly even in demanding environmental and RF conditions.
