Abstract

Systems and methods can support identifying radio transmissions associated with autonomous or remote-controlled vehicles. Radio frequency signals may be received using one or more sensors, wherein the sensors comprise radio receivers. Radio frequency fingerprints may be identified within one or more of the radio frequency signals, wherein the radio frequency fingerprints comprise radio signal characteristics or radio hardware identifiers. A stored radio frequency fingerprint may be determined as matching the received radio frequency fingerprint. A motion characteristic may be computed. The received radio frequency fingerprint may be associated with an autonomous or remote-controlled vehicle based upon the stored radio frequency fingerprint or the motion characteristic. Information regarding the identified autonomous or remote-controlled vehicle may be presenting to one or more operator interfaces.
