Abstract
Radiation is directed between moving vehicles, and the time between transmission and reception of waves, such as microwaves, is determined similarly to radar timing, to determine the spacing between the vehicles. To prevent spurious responses and ambiguities, the signal reflected from the leading vehicle to the trailing vehicle is modulated; modulation can be controlled either automatically, by providing a modulation control signal associated with a given lane of roadway or under driver-command.
