Certainly.hershal said:RADAR - Radio Detection and Ranging . Can we use the same technique on a smaller scale ?
I mean to measure the relative velocity between two vehicles ?
Are there any good sources on internet where I can get information in detail about the working of RADAR system ?
Already here: Mercedes SmartCruiseAstronuc said:Radar systems can be mounted on cars to monitor distance between the cars. Research is underway to look at intelligent crash-avoidance systems.
Pretty slick for the first generation of such devices.Available now in Europe for consumers in both the new S430 and S500, the smart cruise system can maintain a set distance from the vehicle in front as well as a set speed. The S-Class driver sets a desired minimum distance to be maintained behind vehicles ahead, as well as a desired cruising speed. If distance is reduced for any reason (the vehicle ahead slows down, or a brontosaurus enters the lane), the intelligent adaptive cruise control system automatically eases up or applies up to 20% braking power.
A grille-mounted radar sensor monitors the traffic situation ahead up to a distance of 164 yds. (150 m). When the sensor detects a vehicle in front, the interior display shows both vehicles and displays the safe distance via pictograph.
