Object simulation enables ADAS/autonomous-car RADAR evaluation

Vehicle Radar Test System (VRTS) can be used with 76–81 GHz radar technology, from the R&D lab through to high-volume production test; and from individual radar sensors, to integrated advanced driver assistance systems (ADAS). The VRTS is available through select NI Alliance Partners who provide advanced system integration and support.
The VRTS combines NI’s mmWave front end technology, a PXI Vector Signal Transceiver (VST) and application-specific software. Unlike traditional automotive radar simulators that are only capable of obstacle generation for functional behaviour test, the VRTS integrates a 76–81 GHz vector signal generator/analyzer designed for dynamic obstacle generation and comprehensive RF characteristic measurements. Using a more comprehensive approach to radar test that includes both traditional and hardware-in-the-loop (HIL) test techniques, engineers can deliver more robust autonomous driving technology to comply with evolving regulatory requirements.
NI will distribute the VRTS through VRTS Specialty Partners including Hirain Technologies, Konrad Technologies, Linktron and Noffz Computer Technik. VRTS Specialty Partners deliver advanced radar test software and systems that are customized to address exact customer requirements.
The VRTS scales from a base configuration that can emulate two obstacles to sophisticated configurations that can emulate four independent obstacles per PXI chassis. Key VRTS attributes include the ability to simulate Doppler effect velocity of up to 250 km/hr, minimum obstacle range of 4m, object distance resolution down to 10 cm, support for multiple angles of arrival and variable radar cross sections. The VRTS includes both object simulation capabilities and the radar measurement suite.
In addition, engineers can take advantage of the flexibility of the software to use the VRTS to simulate scenarios ranging from a pedestrian walking across the street to lane-change driving scenarios. VRTS software flexibility is a key benefit of the system as engineers can easily adapt to rapidly evolving regulatory environments.
Michael Konrad, Konrad Technologies founder and CEO and cofounder of the ADAS Innovation in Test (IIT) Consortium commented, “The advanced synchronization capabilities of PXI combined with the ease of use of LabVIEW allows us to simulate even some of the most advanced sensor fusion environments combining GNSS, radar, cameras and even lidar.”
