Advanced Radar Sensor


Long-Range Radar

The ARS640 is a high performance premium long range radar sensor which enables highly automated driving in combination with other technologies and the successor of the first 4D imaging radar ARS540. The ARS640 provides best radar performance for critical use cases in urban and highway scenarios. Based on the 5th generation of imaging radars updated cyber security features, sophisticated interference robustness as well as significantly reduced power consumption are realized in the ARS640.
