60 GHz millimeter-wave dual mode radar for IVHS

A dual mode millimeter-wave radar has been proposed for headway control to maintain stable driving on the highway. It would be able to operate in both radar mode, in which it would measure the distance to the leading vehicle, and in communication mode, in which it would exchange data with a vehicle ahead of it. By operating in two modes alternately, the dual mode radar can provide the headway control system with all the data needed to control the distances to the leading vehicles. This paper describes the concept of the dual mode radar system and the results of the experiments undertaken.
