00:00:00 over-the-air radar in the loop simulation dspace toolchain for a Dass and autonomous driving advanced driver assistance systems a dass reduce the number of accidents and can save lives many of these systems rely on radar sensors validating radar sensor functions is a very challenging task to help customers master this challenge dspace provides a solution for testing

00:00:31 radar based aid as functions accurate simulation models and then easy-to-use graphical editor let you create reproducible maneuvers and realistic traffic scenarios the dspace collects EO simulator system controls the radar test bench which consists of the device under test in an anechoic chamber drive parts and a digital radar target simulator to test the entire system including the

00:01:02 radio frequency components real radar echoes of simulated objects are provided over-the-air continuous incoming radar chirps are processed extremely fast an accurate simulation model adds information about the simulated objects to the returning signal to simulate the lateral movement of the simulated objects stacked rings move the antennas precisely to the corresponding

00:01:32 angle the signal strength is automatically adapted according to the distance and the size of the objects multiple fully independent objects can be simulated with darts the simulation setup includes a front radar which is mounted at the front of the virtual ego vehicle the green dots symbolize simulated objects detected by the radar sensor

00:02:11 these simulated vehicles provide the basis for manipulating the reflection echo at each simulation step the antennas are moving very quickly so even cross traffic with high lateral speed can be tested due to its cylindrical shape the test bench covers a very wide angle state-of-the-art drive technology ensures highly dynamic movements

00:02:40 radar in the loop simulation makes it easy to test functions for autonomous driving safely and efficiently this solution stands out for its flexibility and optimized properties this very compact and mobile solution allows for real-time closed-loop testing of the complete chain of effects including bumper impact the powerful dspace tool chain assists you during the

00:03:10 preparation and around-the-clock execution of reproducible test scenarios for a Dass and autonomous driving dspace embedded success
