RADAR GUNN: APPLICATIONS TO HIGHWAYS

LES RADARS GUNN: APPLICATIONS ROUTIERES

The author reviews the applications of the new semi-conductor hyperfrequency devices, called gunn diodes, to cars. Their small dimensions and competitive price enable detection systems to be devised for car application such as sensors (traffic flow, traffic count with recording of direction, speed measurement, recording of obstacles, control of weights, etc.) and at a later stage, for detecting obstacles in the fog (assistance in braking, vehicle spacing for preventing collisions, speed measurements, vehicle identification, etc.). /TRRL/
