    Abstract: Systems and methods for automated unmanned aerial vehicle recognition. A multiplicity of receivers captures RF data and transmits the RF data to at least one node device. The at least one node device comprises a signal processing engine, a detection engine, a classification engine, and a direction finding engine. The at least one node device is configured with an artificial intelligence algorithm. The detection engine and classification engine are trained to detect and classify signals from unmanned vehicles and their controllers based on processed data from the signal processing engine. The direction finding engine is operable to provide lines of bearing for detected unmanned vehicles.

    Abstract: To provide a novel and improved control device and storage medium capable of performing control based on a positional relation with higher accuracy.
    A control device includes a control unit configured to perform control based on a presence area of a first communication device determined using a signal transmitted and received between the first communication device and at least one second communication device. The control unit performs control related to an operation of a controlled device in accordance with a second presence area when a first presence area determined based on a coordinate position of the first communication device on an arbitrary coordinate system associating the first communication device with the second communication device is inconsistent with the second presence area determined based on a distance between the first and second communication devices.

    Abstract: A receiver circuit is disclosed. The receiver circuit includes a receiver antenna or a receiver antenna arrays oriented at a receiver orientation angle and configured to receive a plurality of RF signals transmitted from a transmitter circuit including a transmit antenna or a transmit antenna array oriented at a transmitter orientation angle. A controller A) calculates first and second AoAs based on a first signal at a first receiver antenna array, and calculates third and fourth AoAs based on a second signal at a second receiver antenna array, and/or B) calculates first and second AoDs based on a third signal from a first transmit antenna array, and calculates third and fourth AoDs based on a fourth signal from a second transmit antenna array. The controller also determines which of the first and second AoAs is correct, and/or determines which of the first and second AoDs is correct.

    Abstract: The present disclosure provides satellite tracking systems and tracking methods. The satellite tracking system includes an array of antenna elements and a control unit. A feed current for each of the antenna elements passes through a phase shifter. The control unit generates a control signal for the phase shifter. The satellite tracking system searches, positions, and tracks a target satellite in accordance with the control signal. The satellite tracking systems and methods utilize step scanning and particle swarm optimization in the search stage, compensating for gaps formed during the satellite searching in the positioning stage, and conical scanning in the tracking stage.
