About

Radar sensors for automotive

Radar sensors are an integral part of ADAS in modern cars. While radar sensors are especially vital for autonomous vehicles, they also improve safety and comfort features for drivers. Radar sensors for cars are typically deployed for blind spot detection (BSD), lane change assistance (LCA), collision mitigation (CM), parking aid (PA), and rear cross traffic alert (RCTA) features. Infineon offers a wide variety of automotive radar sensors including short-, mid-, and long-range radar sensors.

RASIC™ 77/79 GHz front-end radar sensor ICs

As part of our comprehensive XENSIV™ family of sensors, we offer a range of RASIC™ 77/79 GHz front-end radar sensor ICs specifically for driver assistance systems, such as adaptive cruise control and collision warning. Capable of detecting and recognizing objects at a range of up to 250 m, these RASIC™ solutions enable the driver assistance capabilities required to obtain a five-star rating from Euro NCAP (European New Car Assessment Program). In fact, our 77/79 GHz SiGe RASIC™ chips lead the MMIC segment. The RASIC™ 77/79 GHz automotive radar support ASIL C, reducing customer R&D efforts.
