초록 ▼

An identification friend or foe (IFF) system and method can covertly identify an object as friend or foe (FoF). An encoded illumination signal can be calculated using a detected ambient signal and an identification (ID) signal and emitted. The encoded illumination signal can be detected by analyzing

대표청구항 ▼

1. A covert identification system comprising: an ambient detector configured to detect a first ambient light signal from a first location on an outer surface of an object;an emitter configured to emit a second ambient light signal from a second location on the outer surface of the object; anda first processor coupled to the ambient detector and the emitter, the first processor configured to: (1) receive the first ambient light signal from the ambient detector;(2) calculate an encoded illumination signal using the received first ambient light signal and an identification (ID) signal; and(3) output the encoded illumination signal to the emitter for emitting the second ambient light signal using the encoded illumination signal;wherein the ID signal in the second ambient light signal output by the emitter is undetectable in the absence of a specified key. 2. The system of claim 1, wherein the encoded illumination signal includes at least a portion of the detected first ambient light signal. 3. The system of claim 1, wherein the first location on the outer surface of the object is adjacent to the second location on the outer surface of the object. 4. The system of claim 1, wherein the first location on the outer surface of the object is opposite to the second location on the outer surface of the object. 5. The system of claim 1, wherein the emitter includes an array of quantum dot light emitting diodes (QDLEDs) configured to be attached to the outer surface of an object. 6. The system of claim 1, wherein the ID signal includes a covert ID signal. 7. The system of claim 6, wherein the covert ID signal includes a signal below a noise floor. 8. The system of claim 1, including: a friend or foe (FoF) detector configured to detect the second ambient signal; anda second processor configured to analyze the detected second ambient signal to: (1) detect the encoded illumination signal; and(2) decode the ID signal from the detected encoded illumination signal using the specified key. 9. A covert identification system comprising: means for receiving an ambient light signal at a first location on an outer surface of an object;means for calculating an encoded illumination signal using the ambient light signal and an identification (ID) signal; andmeans for outputting the encoded illumination signal from a second location on the outer surface of the object such that the ID signal in the encoded illumination signal is undetectable in the absence of a specified key. 10. A covert identification method comprising: detecting a first ambient light signal with an ambient detector at a first location on an outer surface of an object;receiving, at a processor, the first light ambient signal from the ambient detector;calculating, with the processor, an encoded illumination signal using the first ambient light signal and an identification (ID) signal;outputting the encoded illumination signal to an emitter; andemitting the encoded illumination signal from the emitter at a second location on the outer surface of the object;wherein the ID signal in the encoded illumination signal output by the emitter is undetectable in the absence of a specified key. 11. The method of claim 10, wherein the emitting the encoded illumination signal includes emitting at least a portion of the detected first ambient signal. 12. The method of claim 10, wherein the detecting from the first location on the outer surface of the object includes detecting from a location adjacent to the second location on the outer surface of the object. 13. The method of claim 10, wherein the detecting from the first location on the outer surface of the object includes detecting from a location opposite to the second location on the outer surface of the object. 14. The method of claim 10, wherein the calculating the encoded illumination signal using the ID signal includes using a covert ID signal. 15. The method of claim 14, wherein the using the covert ID signal includes using a signal below a noise floor. 16. The method of claim 10, wherein the emitting the encoded illumination signal includes using an array of quantum dot light emitting diodes (QDLEDs) configured to be attached to an outer surface of an object. 17. The method of claim 10, including: detecting a second ambient signal;analyzing the second detected ambient signal to detect the encoded illumination signal; anddecoding the ID signal from the detected encoded illumination signal using the specified key.
