dSpace has supplied the first radar test benches fitted with the latest dSpace Automotive Radar Test System (Darts). They allow for over-the-air simulation of the radar sensor in order to test the entire chain of effects. The test benches incorporate all the software and hardware layers into the tests, from detecting the signal at the front-end of the radar sensor to evaluating it in the radar control unit. The main components of the test benches include an anechoic chamber with send and receive functionality, a calibration, and an in-house Scalexio HiL simulator. During the tests, the radar sensor is stimulated in the anechoic chamber with up to five radar echoes. The coherent echoes allow the radar control unit to measure the distance and the velocity of the radar objects reliably. The concentric movement of the antennas provides information about their azimuth angle. The configurable test benches can be used with 24, 77, and 79 GHz radar sensors in all modulation schemes.
