determining, from known examples of benign and malicious devices stored in a signal signature database, matches to the received radio frequency fingerprint;
computing a time sequence of locations associated with received radio frequency fingerprint based upon received signal strengths from two or more of the one or more sensors;
computing a motion characteristic associated with the potentially malicious, autonomous or remote-controlled vehicle from the computed time sequence of locations;
classifying the potentially malicious, autonomous or remote-controlled vehicle as benign or malicious based upon one or both of the received radio frequency fingerprint or the motion characteristic matching the known examples of malicious devices stored in the signal signature database; and
presenting, via one or more operator interfaces, information regarding the classifying of the potentially malicious, autonomous or remote-controlled vehicle.

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.
