The disclosed invention uses artificial intelligence (AI) algorithms for detecting and classifying radiofrequency (RF) transmissions to assemble a target signal library containing information about one or more target signals according to several criteria. A signal generator develops a mimic signal, designed to emulate a target signal based on information stored in the target signal library. In some embodiments, AI or machine learning (ML) algorithms further assist in refining the mimic signal to more effectively resemble the target signal. Such signal mimicry is done while maintaining small SWaP-C footprint for system component hardware.

A multi-user (MU) multiple-input/multiple-output (MU MIMO) module for a fifth-generation (5G) software-defined radio (SDR) network environment is disclosed. In embodiments, the MU MIMO module of a transmitting SDR system of a 5G mobile ad hoc network (MANET) or other peer-to-peer directional network receives feedback from a receiving SDR system based on a prior or current frame and generates, based on the feedback, a compound transmission security (TRANSEC) encryption key for a subsequent frame. The compound TRANSEC encryption key encrypts the transmission of the subsequent frame through a combination of frequency-hopping encryption codes, orthogonality-hopping encryption codes, and dynamic pseudorandom distribution of transmitting power among antenna elements to simulate multipath hopping. The SDR system may include an antenna controller capable of managing dynamic power distribution according to the compound TRANSEC encryption keys as well as directionality shifts and beamforming operations to evade jammers detected within the 5G network environment.

According to an embodiment, a communication control device includes a communication unit and a jamming control unit. The communication unit wirelessly communicates with a first device and uploads information acquired from the first device to a second device via a network. The jamming control unit allows jamming radio waves to be output to interfere with wireless communication between the first device and a device other than the communication control device, the device being to perform wireless communication in a communication band used by the first device.

A signal generator device includes a digital signal waveform generator to produce a digital signal waveform, a first frequency band signal path having a first frequency band filter to receive the digital signal waveform and to pass first frequency band components of the digital signal waveform, and a first digital-to-analog converter to receive the first frequency band components of the digital signal waveform and to produce a first frequency band analog signal, a second frequency band signal path having a second frequency band filter to receive the digital signal waveform and to pass second frequency band components of the digital signal waveform, a second digital-to-analog converter to receive the second frequency band components of the digital signal waveform and to produce a second frequency band analog signal, and a combining element to combine the first frequency band analog signal and the second frequency band analog signal to produce a wideband analog signal. A method of generating a wideband analog signal includes generating a digital waveform, splitting the digital waveform into at least a first frequency band signal and a second frequency band signal, converting the first frequency band signal into a first frequency band analog signal, converting the second frequency band signal into a second frequency analog signal, and combining the first frequency band analog signal with the second frequency band analog signal to produce the wideband analog signal.

A radio frequency (RF) filter includes a signal conditioning circuit and a bandstop filter. The signal conditioning circuit receives a broadband RF signal that includes both a jamming signal at a jamming frequency and a signal of interest and generates a plurality of clock signals. Each of the plurality of clock signals has a substantially same frequency as the jamming frequency, but a different phase shift. The bandstop filter receives the RF signal and the plurality of clock signals. The bandstop filter attenuates signals within a bandstop centered at the frequency of the plurality of clock signals. A self-tuning N-path filter is provided.

A system for providing integrated detection and deterrence against an unmanned vehicle including but not limited to aerial technology unmanned systems using a detection element, a tracking element, an identification element and an interdiction or deterrent element. Elements contain sensors that observe real time quantifiable data regarding the object of interest to create an assessment of risk or threat to a protected area of interest. This assessment may be based e.g., on data mining of internal and external data sources. The deterrent element selects from a variable menu of possible deterrent actions. Though designed for autonomous action, a Human in the Loop may override the automated system solutions.

A method to detect and jars an electromagnetic transmission includes detecting electromagnetic radiation from an electromagnetic radiating source, determining the type of the received electromagnetic radiation by comparing the signature of the received signal with signatures from a database, selecting the waveform and frequency to disturb the determined type, and transmitting a waveform with a frequency to jam the electromagnetic transmission. A system to jam an electromagnetic transmission is also provided.

A portable countermeasure device is provided comprising one or more directional antennae, one or more disruption components and at least one activator. The portable countermeasure device further comprises a body having a dual-grip configuration, with the directional antennae are affixed to a removable plate on a front portion of the body. The one or more disruption components may be internally mounted within the device body. The dual-grip configuration allows an operator to use his body to steady and support the device while maintaining the antenna on target. The second grip is positioned adjacent the first grip, with the first grip angled toward the rear of the device and the second grip angled toward the front of the device. The portable countermeasure device is aimed at a specific drone, the activator is engaged, and disruptive signals are directed toward the drone, disrupting the control, navigation, and other signals to and from the drone.
