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.

Embodiments of the present disclosure utilize signals generated by a radio frequency identification (RFID) antenna to locate the antenna. For example, a signal emitted by a transmitter can cause an unpowered mobile device's RFID antenna to generate return signals that are received by multiple antennas. Time difference of arrival (TDOA) and a frequency difference of arrival (FDOA) values can be calculated for the received signals. The calculated TDOA and FDOA values can be correlated using a cross ambiguity function (CAF). The correlated values can be plotted on a map to create a set of correlation maps. The correlation maps can be combined to produce an average map and the antenna can be located by identifying a maximum correlation value on the average map.
