1. An identification method performed by an unmanned aerial vehicle (UAV) detection apparatus, the identification method comprising:
transmitting a radar signal for detecting a UAV, based on a detection distance of the UAV detection apparatus;
detecting a plurality of UAVs existing within the detection distance according to a radar signal reflected from each of the plurality of UAVs;
transmitting an identification information request message to each of the detected plurality of UAVs;
receiving, via a unicast communication scheme or a broadcast communication scheme, an identification information response message from a UAV that receives the identification information request message;
comparing a number of identification information response messages that are received and a number of identification information request messages that are transmitted to the plurality of UAVs; and
transmitting a transmission completion message to a UAV that transmits an identification information response message, based on a result of the comparing,
wherein the identification information response message includes a drone identification number (DIN).
