Radar Sensor Architecture and Technologies English Free

Accident statistics show that 76% of accidents are the fault of drivers, and in 94% of accidents, some human error is involved.
Radar based driver assistance systems already play an important role for applications like ACC (Automatic Cruise Control), pedestrian protection, blind spot monitoring, collision warning, cross traffic alert, lane change support, open door warning on busy street, parking assistance and other new upcoming applications.
Today radar systems are based either on 24GHz or on 77GHz. The benefit of the higher frequency radar systems mainly is the higher  accuracy in terms of distance-, speed-measurement and angular resolution, smaller antenna size and lower risk of mutual interference.

This paper will compare different approaches for the partitioning of a radar system. An overview on feasible RF technologies will be presented, which provide high frequency capabilities as well as the opportunity to realize medium and large scale integration.

STMicroelectronics is producing and developing MMIC’s for 24GHz and 77/79GHz. The actual roadmap of these devices will be shown and explained.

The main advantages and draw backs of different automotive radar frequencies like 24Ghz, 77/79GHz and for the future 122GHz will be highlighted.

INGENIEURS DE L'AUTO SE DIGITALISE

 

 

La revue Ingénieurs de l’Auto est maintenant diffusée en print et on line. Une grande première pour la SIA avec ce numéro 865, disponible au format numérique.

Cette version digitale sera, à chaque numéro, réservée aux membres de la SIA abonnés.

Exceptionnellement pour ce premier numéro on line, et en lien avec la situation de confinement et de télétravail de beaucoup d’ingénieurs de notre industrie, la version digitale du numéro de Mai est accessible à tous.
