Embodiments of communication systems are disclosed for protecting communication between an implanted device ID and an external device ED. Optionally, the ID communicates over the TET channel by modulating a load on the channel. While the ID is communicating the ED optionally adds noise to the TET channel, inhibiting malicious interception of the communication. Using knowledge of the noise signal, the ED cleans the noise from the TET signal to recover the communication from the ID. In some embodiments, the TET link is used to pass an encryption key and/or to verify communications over a radio channel. The TET channel may be authenticated. For example, authentication may include a minimum energy and/or power transfer.

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.

An Unmanned Aerial Vehicle is disclosed. The Unmanned Aerial Vehicle includes a body, rotors attached to the body, one or more sensors, and an electromagnetic pulse transmitter. The electromagnetic pulse transmitter is configured to transmit an EMP and the Unmanned Aerial Vehicle is configured to track a target Unmanned Aerial Vehicle using the one or more sensors and direct the electromagnetic pulse transmitter at the target Unmanned Aerial Vehicle to disrupt the target Unmanned Aerial Vehicle.

Apparatus for establishing a wireless connection with a mobile communication device includes a transceiver arranged to transmit a set of broadcast control signals on a first carrier, thereby to enable the establishing of the wireless connection between the transceiver and the mobile communication device. The apparatus further includes one or more transmitters each arranged to transmit a respective interference signal for interfering with broadcast control signals transmitted on a respective one or more carriers different from the first carrier by a respective one or more base stations of a mobile communications network.

An apparatus of controlled reception pattern antenna (CRPA) neutralization for an illegal unmanned aerial vehicle (UAV) includes an interference signal generator transmitting a direct wave toward a CRPA of an illegal UAV through a first transmission antenna and transmitting a first reflected wave inducing signal through a second transmission antenna and a first passive propagation mirror reflecting the first reflected wave inducing signal toward the illegal UAV so that the first reflected wave propagates toward the CRPA of the illegal UAV.

Techniques for providing a multi-stage iterative scheme to determine fine granularity estimates of parameters of an interfering signal and for using the fine granularity estimates of the parameters to reduce an impact of the interfering signal against a signal of interest (SOI) are disclosed. An input signal is identified. A first set of estimation parameters that provide a coarse granularity estimate of a center frequency of the jamming signal and of a symbol rate of the jamming signal are determined. The first set of estimation parameters are refined to generate a medium granularity estimate of the center frequency and the symbol rate of the jamming frequency. The medium granularity estimates are also refined to produce a fine granularity estimate of the center frequency and the symbol rate. The fine granularity estimates are used to remove or reduce an influence of the jamming signal on the input signal.

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.
