Vehicle Radar Test System helps integrate ADAS
Object simulation and radar measurement capabilities for engineers testing autonomous driving technology are delivered with the Vehicle Radar Test System (VRTS) from National Instruments (NI).
Engineers can use the VRTS to test 76 to 81GHz radar technology from the R&D lab through 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 to 81 GHz vector signal generator/analyser designed for dynamic obstacle generation and comprehensive RF characteristic measurements. This approach to radar test that includes both traditional and hardware-in-the-loop (HIL) test techniques allow engineers to 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 customised to address exact customer requirements.
“We can use the VRTS to configure the industry’s most advanced ADAS test systems to improve the safety and reliability of vehicles,” said Michael Konrad, Konrad Technologies founder and CEO and co-founder of the ADAS Innovation in Test (IIT) Consortium. “The advanced synchronisation 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.”
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 250km/hr, minimum obstacle range of four metres, object distance resolution down to 10omm, 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 also 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.
According to NI, the VRTS empowers engineers to build smarter, highly customised test systems to verify automotive radar sensor performance. Users can also 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.
