77 GHz radar sensors
Invisible assistants: Driver assistance systems increase road safety. Radar sensor technology in particular is becoming increasingly important. Radar sensors record and evaluate object-related speed, bracket, and distance information. They help to detect and warn of dangerous situations at an early stage. The sensors enable 360° detection of moving objects such as pedestrians or vehicles, as well as non-moving surrounding objects. The frequency-modulated continuous-wave (FMCW) radar can be used regardless of weather conditions such as fog, rain, or snow and can detect both distance and relative speed.
The HELLA 77 GHz radar sensors offer high tech in a compact design. The small dimensions and good transmission properties of the 77 GHz technology mean they can be mounted or integrated covertly behind the bumper or on the side of the vehicle. At its heart is a latest-generation system chip based on RF-CMOS technology. Thanks to the special chip architecture, digital components as well as self-diagnostic systems can be integrated in addition to components for transmitting/receiving. HELLA 77 GHz radar sensors have IP 6K7 and IP X 9K protection classes.
