Classification: CPC G  H | IPC G  H

Claim 0:
1. A method of detecting an unmanned aerial vehicle (UAV), the method comprising:
generating a pseudo random binary sequence (PRBS);
performing a time delay on the PRBS using a different offset to generate a photographing time control signal as the control signal for one or more cameras positioned in a UAV protected area;
transmitting the generated photographing time control signal to each of the one or more cameras;
controlling variably photographing time periods and photographing target areas of the one or more cameras;
receiving images from the one or more cameras; and
analyzing the received images to extract a UAV from the received images,
wherein the controlling includes controlling the photographing time periods and the photographing target areas based on the control signal generated by the random sequence including the PRBS.
