5th generation 77 GHz radar sensors smaller with better resolution

November 30, 2017 // By Christoph Hammerschmidt
Automotive supplier Continental has introduced the fifth generation of automotive radar sensors. Since it is active in the 77 GHz frequency band with shorter wavelengths than earlier generations, it offers a higher resolution – it can detect smaller objects on the surface, such as a lost tire or a fallen exhaust pipe. It is based on a scalable modular design principle which, with its graduated functional scope, flexibly supports different requirements and electrical-electronic (E/E) architectures of the vehicle manufacturers.

If implemented as a long-distance sensor, the radar sensor has a range up to 300 meters (1000ft) and aperture angles of 120 degrees. For the first time, short-range radar makes it possible to implement functions such as blind spot warning, lane change assistant and very precise parking functions. With this profile, the sensors are regarded as an important building block for the development of assisted and automated driving functions.

The new sensors are more compact and flexible tan former generations. In addition, through a dedicated interface in the sensor and through its modularity in hardware and software, they can be used either as stand-alone sensor or as a pure “radar head” without an own signal processing.
