Aperçu

Radar sensors are a key technology for the implementation of today’s driver assistance systems and automated driving functions. Due to the safety-critical nature of these systems, they must be thoroughly vetted with testing. One particularly comprehensive method is to use an over-the-air approach. This involves the use of radar target simulators (RTS), whereby the entire signal path of the radar – from the signal generation to the algorithm of the assistance system – is tested and validated. RTSs receive the radar signal, imprint targets on it on the fly and send the manipulated signal back to the radar - fully independent of the concrete waveform used by the radar sensor.

The dSPACE Automotive Radar Test System (DARTS) offers a wide range of RTS for different radar sensors and application scenarios. Covering the whole automotive SRR & LRR band simultaneously, the new DARTS 9040-G is particularly tailored for next-generation ultra-high resolution imaging radars, often referred to as 4D radars. DARTS is applied in all development phases, from chip design and sensor development to end-of-line tests and beyond. Options include:

• A stand-alone system for quick and easy sensor validation
• Integration with a dSPACE Radar Test Bench to realize complex, scenario-based, hardware-in-the-loop tests of single radars and virtual vehicles
• Integration with a vehicle-in-the-loop test for testing driving functions in fully assembled and unmodified vehicles (e.g., during periodical technical inspection)
