Claim 12:
13. A computer program product comprising computer-readable program code to be executed by one or more processors when retrieved from a non-transitory computer-readable medium, the program code including instructions configured to cause:
scanning, with a plurality of scanning apparatuses, a region of airspace associated with a sensitive security area each scanning apparatus comprising one or more directional Radio Frequency (RF) antennae, each of the scanning apparatuses having different locations, at least one of the scanning apparatuses being connected with a moveable vehicle;
processing first radio frequency signals emitted by a first UAV at the scanning apparatuses, a frequency of the first radio frequency signals being a downlink frequency of the first UAV;
processing, based on an angular relationship between the locations of the scanning apparatuses and the first UAV, the first radio frequency signals to determine a first location of the first UAV;
scanning, with an aircraft-mounted scanning apparatus, a region of ground space associated with the sensitive security area, the aircraft-mounted scanning apparatus comprising one or more further directional Radio Frequency (RF) antennae;
processing, at the aircraft-mounted scanning apparatus, radio frequency signals corresponding to an uplink frequency of the first UAV; and
processing, based on an angular relationship between the location of the aircraft-mounted scanning apparatus and a source of the further radio frequency signals, the further radio frequency signals to determine a first location of the source of the further radio frequency signals, the source of the further radio frequency signals being associated with an operator of the first UAV.
