초록 ▼

An interrogator-transponder system in which multiple vehicle mounted transponders which may be closely spaced in distance and moving at similar velocities, respond with a coherent identification code signal that is displaced in frequency from the interrogation signal by an amount that is identical for each transponder. The response signal spacings in time (Pulse repetition intervals) are different for each transponder but are always multiples of the pulse repetition interval of the interrogation signal. A coherent reference for the received transponder codes is obtained by combining the coherent interrogation signal with a coherent reference that is substantially identical in frequency to the displacement frequency of the transponder response signal. Means are provided in the interrogation device to determine the velocity of each transponder and its range with respect to the interrogator and to identify vehicles with inoperative transponders. The resulting data stream of identification codes and associated velocities and ranges may be used for traffic speed enforcement, wanted vehicle search, interactive traffic signal control, automated toll collection, traffic surveys, and identification of friendly forces.

An interrogator and transponder system for identifying and classifying multiple moveable objects comprising, a. at least one interrogator comprising transmitter means, said transmitter transmitting interrogation signal, b. multiple remotely located transponder means each mounted on a moveable object, receiver means in said transponder feeding transponder transmitter means, means in said transponder transmitter for generating a first frequency the same as the received interrogation signal frequency and means for generating a second transponder offset frequency signal that is substantially identical in all transponders, and means for combining said two frequencies to produce a third transponder transmitter carrier frequency signal, c. code generator means in said transponders, each generating a code that is unique to the moveable object on which the transponder is mounted, d. transponder pulse repetition interval generator means for generating a time sequence of transponder pulses, means for causing these pulses to bear a fixed time relationship to an interrogation signal and means for varying the number of interrogation signals between transponder pulses that is unique to each of a multiplicity of transponders, e. means for initiating a transponder transmitter output signal that is coded with said code for each of said transponder pulses, f. receiver and decoder/digital processor means located at each interrogator, said means combining the interrogation transmitter frequency with the frequency output of an interrogation offset frequency generator means, said offset frequency being substantially identical to the transponders offset frequency and means for using the resulting frequency as a reference frequency for measuring the rate of change of phase between the reference signal and the received transponder signals, g. means for converting the measured rate of change of phase into a closing velocity and means for converting the measured time delay into a range distance and means for storing each range and velocity with the associated transponder code.
