Unmanned aerial vehicle detection method using global positioning system leakage signal and system therefor

摘要

An unmanned aerial vehicle (UAV) detection method and a system therefor are provided. The UAV detection method includes receiving a radio signal from air, detecting a global positioning system (GPS) leakage signal of a predetermined frequency from the received radio signal, and determining that a UAV is detected when the GPS leakage signal is detected.

1. An unmanned aerial vehicle (UAV) detection method, comprising:
receiving a reflection signal corresponding to a radio signal using a circular cylindrical active array (CCAA) antenna from air; detecting a global positioning system (GPS) leakage signal of a predetermined frequency from the received reflection signal by detecting one or more GPS leakage signals for at least one of a plurality of different types of UAVs based on preset information about an oscillator associated with each of the plurality of different types of UAVs; determining that a UAV is detected when the GPS leakage signal is detected; and displaying visual information corresponding to the detected UAV responsive to the detection of the UAV.
