1. A method for identifying unmanned aerial vehicles (UAVs) in a particular air space, comprising the steps of: receiving video data from a particular video sensor proximate to the particular air space, the video data including at least one image of an object that may be a UAV flying within the particular air space; analyzing the video data to determine a first confidence measure that the object in the at least one image comprises a UAV; receiving audio signal data from a particular audio sensor proximate to the particular air space, the audio signal data including frequency data indicating a possible presence of a UAV within the particular air space; analyzing the audio signal data to determine a second confidence measure that the frequency data comprises a UAV; receiving radio frequency (RF) signal data from a particular RF sensor proximate to the particular air space, the RF signal data including data indicating a possible presence of a UAV within the particular air space; analyzing the RF signal data to determine a third confidence measure that the RF signal data corresponds to a UAV; aggregating the first confidence measure, the second confidence measure, and the third confidence measure into a combined confidence measure indicating a possible presence of a UAV in the particular air space; and upon determination that the combined confidence measure exceeds a predetermined threshold value, storing an indication in a database that a UAV was identified in the particular air space.
