    Radar Echo Generation by Rohde and Schwarz

    Explore the Latest Automotive Technologies and Solutions from Rohde and Schwarz exclusively at Auto EV India 2022 from 9th to 11th November 2022 at KTPO Bengaluru.

    Developing new automotive radar sensors, radar-based Advanced Driver Assistance Systems (ADAS), or Autonomous Driving (AD) features have demanding challenges, during each step of the development process. Dynamic, flexible, and scalable test concepts and test environments are required.

    The R&S®AREG800A Automotive Radar Echo Generator together with the R&S®QAT100 advanced antenna array is an advanced and innovative key enabler for testing automotive radar sensors and ADAS/AD features. When operated together, independent artificial objects can be generated with individual object distance, object size, radial velocity and angular direction. This enables for the first time the generation of realistic driving scenarios for automotive radar sensors during development and ADAS/AD feature tests.

    The R&S®AREG100A Automotive Radar Echo Generator is a robust solution tailored for the production testing of automotive radar sensors. With the R&S®AREG100A, production engineers profit from a perfect balance of flexibility of test cases and at the same time simple and robust operation.
