Methods for radio frequency spectral analysis
Patent number: 10374732
Abstract: The invention is directed to methods for radio frequency spectral analysis. Accordingly, flight instructions are executed on a first UAV to fly in a first flight pattern relative to a signal source. The first UAV detects radio signal(s) from the signal source and associated signal data. Flight instructions are concurrently executed on a second UAV to fly in a second flight pattern, relative to the first flight pattern of the first UAV. The second UAV also detects radio signal(s) from the signal source and associated signal data. The stored signal data from the drones may then be processed for visualization.
System and method for detecting and defeating a drone
Patent number: 10234857
Abstract: 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.

UAV, system, and method for radio frequency spectral analysis
Patent number: 9797978
Abstract: The invention is directed to a UAV, system, and method for radio frequency spectral analysis. Accordingly, an unmanned aerial vehicle (UAV) having a flight body, a flight module, a geolocation module, and a signal detection module is utilized to detect and store signal data associated with various radio signal(s) during flight. The signal data may then be displayed on a processing device to provide a user with a visualization of the signal data parameters in various points of three dimensional space and at particular recorded times.
System and method for detecting and defeating a drone
Patent number: 9529360
Abstract: The invention is directed to a system for detecting and defeating a drone. The system has a detection antenna array structured and configured to detect the drone and the drone control signal over a 360 degree field relative to the detection antenna array including detecting the directionality of the drone. The system also includes a neutralization system structured and configured in a communicating relation with the detection antenna array. The neutralization system has a transmission antenna structured to transmit an override signal aimed at the direction of the drone, an amplifier configured to boost the gain of the override signal to exceed the signal strength of the drone control signal, and a processing device configured to create and effect the transmission of the override signal. The invention is also directed to a method for detecting and defeating a drone.
Cell phone control and localization for restricted facilities
Patent number: 8750903
Abstract: A method and system for controlling cell phones and cellular phone system based wireless devices in a restricted environment, such as prisons, where the control system makes use of software defined radios to mimic the ambient wireless signals transmitted from nearby cell phone base stations. The system produces a multi-protocol beacon set based on the existing wireless environment and a pre-determined logic set to accomplish complete coverage of all relevant cell phone operating protocols. Cell phones within the desired target coverage area are then attracted to the system and their operation can be controlled. The cell phone control system is able to selectively deny or permit calls based upon a whitelist/blacklist database. The cell phone control system is interfaced to a distributed system of antennas in order to provide the proper control needed over the coverage area.
Wireless communication jamming using signal delay technology
Patent number: 8543053
Abstract: A device and method for jamming wireless communication devices where the jamming signal is derived from the downlink signal of the base station and processed with a time delay sufficient length as to prevent the base station receiver from correctly processing the responding uplink signal from the targeted wireless communications device. Such wireless communication jamming device can be used by law enforcement and authorized government entities to block the operation of wireless communication devices such as cell phones within a target area.
