Cross-modality electromagnetic signature analysis for radio frequency persona identification

摘要

Systems and methods can support identifying multiple radio transmitters as being integrated within a single communications device. Radio frequency signals may be collected using one or more sensors incorporating radio receivers. A first radio frequency signature and a second radio frequency signature may be identified within one or more of the radio frequency signals as originating respectively from a first radio transmitter and a second radio transmitter. Characteristics of the first and second radio frequency signatures may be analyzed to evaluate a relationship between the first and second radio frequency signatures. It may be determined whether or not the first and second radio transmitters are integrated within a common wireless electronic device based upon the evaluated relationship between the first radio frequency signature and the second radio frequency signature. Characteristics and behaviors associated with the wireless electronic device may be determined therefrom.

1. A method for identifying multiple radio transmitters within a single wireless communications device, comprising:
receiving radio frequency signals using one or more sensors, wherein the sensors comprise radio receivers; identifying a first radio frequency signature within one or more of the radio frequency signals as originating from a first radio transmitter; identifying a second radio frequency signature within one or more of the radio frequency signals as originating from a second radio transmitter; analyzing characteristics of the first radio frequency signature and of the second radio frequency signature to evaluate a relationship between the first radio frequency signature and the second radio frequency signature; determining if the first radio transmitter and the second radio transmitter are integrated together within the single wireless communications device based upon the evaluated relationship between the first radio frequency signature and the second radio frequency signature; and determining operational characteristics associated with the single wireless communications device in response to determining that the first radio transmitter and the second radio transmitter are integrated within the single wireless communications device.
