Abrégé

Described herein are systems and methods for detecting microwave pulses. An example method may include identifying, by a first sensor, a first signal in an environment, the first signal including a signal in a microwave frequency range. The example method may also include determining first data associated with the first signal, the first data being associated with one or more parameters. The example method may also include determining that the first data exceeds a threshold. The example method may also include sending, based on the determination that the first data exceeds a threshold, an alert.

Abrégé

Systems and methods can support determining a physical position of a radio transmitter. A physical model for electromagnetic signal propagation within the electromagnetic environment may be established. Radio frequency signal power levels associated with the radio transmitter may be received from one or more radio frequency sensors. Parameters associated with the physical model may be estimated for one or more test locations within the electromagnetic environment. An error metric between the received radio frequency signal power levels and the physical model may be computed for the one or more test locations. Bounds on the parameters associated with the physical model may be established to prune away physically impossible solutions. The parameters associated with the physical model may be optimized across the one or more test locations to establish a preferred location estimate for the radio transmitter.

Electromagnetic (EM)/radio frequency (RF) emissions may be detected and corresponding EM personas may be created. One or more EM personas may be associated with a super persona corresponding to a particular entity. EM personas, super personas, and/or supplemental identifying information can be used to enforce security protocols.

Abrégé

Systems and methods can support threat detection using electromagnetic signatures. One or more sensors comprising radio receivers may receive radio frequency signals within an electromagnetic environment. Radio frequency signatures may be identified from one or more of the radio frequency signals. A baseline electromagnetic environment may be established from the radio frequency signatures. The radio frequency signatures may be monitored over time to detect variations from the baseline electromagnetic environment. Variations in the electromagnetic environment may be evaluated against stored threat signatures. Operator interfaces may present indications of threats determined from evaluating the variations in the electromagnetic environment.
