A system for detecting and defeating a drone is disclosed which includes a detection antenna array configured to detect the drone and a control signal of the drone in a 360 degree field, the detection antenna array being further configured to detect the directionality of the drone with reference to the most dominant of the control signal of the drone detected by each of a plurality of antennas within the detection antenna array; a neutralization system disposed in communication with the detection antenna array; the neutralization system including a transmission antenna configured to transmit an override signal to the detected drone, an amplifier configured to modulate a gain of the override signal, and a processing device configured to generate the override signal and control transmission of the override signal.

A system for providing integrated detection and deterrence against an unmanned vehicle including but not limited to aerial and similar 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 the object of interests risk or threat to a protected area of interest. This assessment is based on the application of machine learning and data mining techniques and protocols to the set of data related to the object of interest. This data product is available to third parties via a set of defined interface protocols and available API. The deterrent element, using other machine learning or artificially intelligent algorithms, selects from a variable menu of possible deterrent actions not limited to those actions currently included in this embodiment, but includes those actions available from third parties such as specialized hunter drones. Though designed for autonomous action, a Human in the Loop may override the automated system solutions.

A system for providing integrated detection and countermeasures against unmanned aerial vehicles include a detecting element, a location determining element and an interdiction element. The detecting element detects an unmanned aerial vehicle in flight in the region of, or approaching, a property, place, event or very important person. The location determining element determines the exact location of the unmanned aerial vehicle. The interdiction element can either direct the unmanned aerial vehicle away from the property, place, event or very important person in a non-destructive manner, or can cause disable the unmanned aerial vehicle in a destructive manner.

A wave construction method is described that can be used to generate a new and different wave front, which is not parallel to the natural expanding wave front from the emitted signal generated from the source array. Restated, a wave construction method is described that can be used to generate a new and different wave front which is not perpendicular to the direction from the source array to the center of the wave front. This method can also be used to shape a wave in the far field or near field, by changing the locations of the computed points, and generating a linear or non-linear shaped wave (front). This disclosure allows for the controlling, rotating, or shaping radio frequency or acoustic waves in free space or in a fluid.

A method for finding an orthogonal direction of a radiation source with respect a digitally optimized interference pattern of a first fixed electromagnetic element and a second fixed electromagnetic element has been established. Determining a direction of a radiation source allows for dynamic control of moving object.

A system detects and identifies unmanned vehicles (UVs) from radio communications between UVs and their controllers. One or more radio frequency (RF) signal detectors can detect RF signals, including downlink signals transmitted by a UV or uplink signals transmitted by a UV controller. A feature extractor can extract signal features from detected RF signals, and a classifier performs machine learning to identify at least one of the UV and the UV controller based on the signal features. Machine learning can employ an artificial neural network, which may perform deep learning.

A method for jamming airborne SAR radar implemented by a jamming device includes at least two cooperating units surrounding an area on the ground to be protected, at least two units providing a radar-detection function and at least one unit providing a radar-jamming function, each unit being interlinked by a two-way data link and being synchronized by a common clock, the method comprises a step of identifying the signals received and whether the received signals correspond to SAR signals; a step of characterizing the received SAR signal over a short duration; a step of computing a filter adapted to the signal; a step of carrying out pulse compression of the signal; a step of iteratively periodically characterizing the signal over a long duration; a step of computing the jamming signals to be transmitted; a step of transmitting the jamming signals.

A system and method of improving data link performance between two or more wireless data transceivers includes: clipping and inverting the data components of a communication signal which are calculated to cause non-linear saturation effects in the downstream power amplifier; delaying a first time series to align the first time series with the clipped and inverted data components of a second time series; adding the clipped and inverted data components of the second time series to the delayed first time series to obtain a modified composite waveform; creating a sacrificial band containing principal energy of the clipped and inverted data components of the second time series; harvesting the principal energy of the sacrificial band to obtain an optimized composite waveform; and causing the composite waveform to produce non-linear distortion to optimize the harvested principal energy.
