APPARATUS AND METHOD FOR DETECTING A SMALL UNMANNED AERIAL VEHICLEUAV

摘要

The present invention is to provide an apparatus and method for more effectively detecting a small unmanned aerial vehicle, and a signal receiver for receiving a radar signal including a target signal, and a range for acquiring a range profile from the received target signal a profile obtaining unit; a constant false alarm rate (CFAR) detecting unit detecting, as a range bin, a partial range having an amplitude exceeding a preset first threshold value as a range bin, based on the obtained range profile; a spectrum signal generator for generating a frequency spectrum signal by extracting a signal of the detected range bin; and, based on the frequency spectrum signal, an amplitude exceeding a second threshold determined based on a preset weight and a noise variable is detected and a control unit for detecting the number of detected frequencies and determining whether a target corresponding to the target signal is an unmanned aerial vehicle based on whether the number of detected frequencies exceeds a preset threshold number of signals.
