NI Technology Improves Safety, Reliability Test for ADAS and Autonomous Vehicles

October 11, 2017

NI announced the Vehicle Radar Test System (VRTS), enabling engineers to test 76 to 81 GHz radar technology from R&D through high-volume production, from individual radar sensors to integrated advanced driver assistance systems (ADAS). 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.

The VRTS combines NI’s millimeter wave 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 behavior test, the VRTS integrates a 76 to 81 GHz vector signal generator and analyzer designed for dynamic obstacle generation and comprehensive measurement of RF characteristics.

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 up to 250 km/hr, minimum obstacle range of 4 m, object distance resolution down to 10 cm and support for multiple angles of arrival and variable radar cross sections. The VRTS includes both object simulation capabilities and the radar measurement suite.

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. VRTS software flexibility is a key benefit of the system as engineers can easily adapt to rapidly evolving regulatory environments.

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 customer requirements.

Michael Konrad, Konrad Technologies founder and CEO and co-founder of the ADAS Innovation in Test (IIT) Consortium, said, “We can use the VRTS to configure the industry’s most advanced ADAS test systems to improve the safety and reliability of vehicles. 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.”

Users benefit from the productivity of the LabVIEW, VeriStand and TestStand software environments, along with a vibrant ecosystem of partners, add-on IP and applications engineers to help dramatically lower the cost of test, reduce time to market and future proof testers for tomorrow’s challenging requirements.
