The R&S®QAT100 from Rohde & Schwarz is a mmWave Antenna Array for automotive radar testing system that operates from 76 to 81 GHz. It has an electronically steerable frontend that enables realistic target generation. The antenna array has up to 2 x 96 individually switchable transmit antennas and can simulate up to 8 completely independent objects. It has small patch antennas which are covered with an absorber to provide a clean RF frontend with very low RCS, reducing the sensor noise floor and suppressing close range targets and potential multipath reflections.
The R&S®QAT100 has an antenna spacing of 3.7 mm that provides a high angular resolution for the realistic simulation of complex radar scenarios. With electronic switching of the antennas, it is possible to accurately simulate extremely high angular velocities with complete reproducibility. Multiple R&S®QAT100 can be combined to increase the field of view. Synchronization of all R&S®QAT100 arrays in a multi-instrument advanced antenna array setup is ensured by the R&S®AREG800A dynamic radar echo generator, enabling the simulation of complex ADAS scenarios.
