Object simulation for ADAS safety and reliability testing

October 19, 2017 // By Julien Happich
National Instruments' Vehicle Radar Test System (VRTS) allows engineers 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 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 behavior 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 specialty partners including Hirain Technologies, Konrad Technologies, Linktron and Noffz Computer Technik, all able to deliver advanced radar test software and systems that are customized to address exact customer requirements.

Built on a flexible software and modular hardware platform, 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 4m, object distance resolution down to 10cm, 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.
