Claim 8:
9. A system for detecting unmanned aerial vehicles (UAVs) in a sensitive security area, the system comprising:
a plurality of scanning apparatuses, each scanning apparatus comprising an array of one or more directional antennae configured to receive radio frequency signals having a designated frequency, the array of directional antennae having a spatial configuration, at least one of the scanning apparatus being connected with a moveable vehicle, each scanning apparatus being configured to:
receive radio frequency signals associated with one or more UAVs, a frequency of each radio frequency signal being a downlink frequency of a corresponding UAV;
determine a signal strength associated with each of the radio frequency signals; and
generate, using the signal strength and the spatial configuration, data indicating an angular relationship between a location one of the plurality of scanning apparatuses and the corresponding UAV;

one or more processors in communication with each of the scanning apparatuses, the one or more processors operable to:
receive data from at least two of the plurality of scanning apparatuses;
process, using locations of the at least two ground data terminals, the data from the at least two scanning apparatuses to determine a location of a first UAV;
track both the UAV and the second UAV; and

an aircraft-mounted scanning apparatus comprising one or more further directional Radio Frequency (RF) antennae, the aircraft mounted scanning apparatus being configured to:
scan a region of ground space associated with the sensitive security area, and
receive radio frequency signals corresponding to an uplink frequency of the first UAV; and

the one or more processors being further operable to:
process, 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 radio frequency signals being associated with an operator of the first UAV.
