Abstract
A vehicle-to-vehicle communications system utilizes passive modulation of radar signals to communicate information between vehicles. Passive radar modulators may be provided at the rear of a forward vehicle and used to enrich radar interrogation signals from a rearward vehicle with additional information. Since radar transceivers are already located on a great deal of modern vehicles, this functionality may be easily retrofitted into many vehicles without the addition of a radar transceiver. A number of vehicles in a line of vehicles may pass information back through the line by passive modulation of radar interrogation signals from each vehicle. Accordingly, a vehicle may gain information about vehicles ahead of the one directly in front of it, thereby enabling 'see through radar' functionality.
