Automotive Radar ADAS Test Solution Simplifies and Shortens Radar Sensor Development Time and Production Testing

Konrad Technologies has released a new advanced system integration for the NI VRTS (Vehicle Radar Test System), an automotive radar test solution for the rapidly expanding autonomous vehicles industry. The new Konrad ARTS test solution provides a significantly more robust and capable test architecture that simplifies and shortens radar sensor development time, production test and functional verification in a HIL test.

The Konrad ARTS (Automotive Radar Test Solution) is a customizable and configurable radar test system. Users can validate backend sensor algorithms and increase the realism of radar test by confronting the sensor with multiple versions of real-world scenarios. The system can be deployed for RF measurement-based and object simulation test methodologies to meet exact production, validation or HIL test specification needs. It empowers production and validation test engineers by combining radar test measurements and custom object scenarios, including NCAP scenarios, for radar sensor functional verification, in one system.

The Konrad Target Simulation Software for radar sensors is designed for short and long-range radar sensors and leverages the NI VRTS (Vehicle Radar Test System). The NI VRTS consists of mmWave front-end technology, a Vector Signal Transceiver (VST) and NI-5692 Variable Delay Generator (VDG). The system is designed to test 24 GHz/76-81 GHz radar band with 1 GHz of real-time bandwidth.

Active Safety Systems require millions of test-drive kilometers to meet all industry standards. Acquiring road data is extremely expensive, increasingly time-consuming and offers no guarantee that all test driving scenarios are covered. Users can now test critical safety systems in the lab with the Konrad ARTS, a future-proof ADAS test solution. Based on this collaborative software and hardware test system, ADAS technologies and control systems can be tested in a SIL (Software-in-the-Loop), HIL (Hardware-in-the-Loop) or DIL (Driver-in-the-Loop) fashion. Testing can be conducted in real-time and supports a broad range of different applications. These tests provide a high degree of consistency across the various stages of development.

The demand for ADAS test capabilities leading to fully autonomous driving cars requires comprehensive test systems that combine the inputs of all car sensors from camera and lidar to radar. To solve these challenges and speed innovation, NI partners Konrad Technologies GmbH, SET GmbH, S.E.A. Datentechnik GmbH, measX GmbH & Co. KG formed a collaboration - ADAS IIT - Innovation in Test – leveraging their expertise in the field of ADAS, sensor fusion, HIL, V2X communication, GNSS simulation and data management to provide a one-stop solution for fully autonomous vehicle test.

The ADAS IIT group is the first to present an all-inclusive sensor fusion testing capability on a single platform. This unique NI platform based concept will help bring autonomous vehicles to the market safer and faster than expected. The consortium is dedicated to providing future-proof ADAS test solutions to accelerate development programs for leading vehicle manufacturers worldwide.

Konrad has already showcased the Konrad ARTS for performing RF measurements and target simulation for radar sensors. The Konrad ARTS can be extended to a HIL with sensor fusion solution including lidar, radar and camera sensors. The virtual test drive applications perform sensor fusion testing using IPG Carmaker and NI VeriStand running on an NI HIL. This allows users to test and replay complex driving scenarios.
