Abstract
Disclosed are examples of systems, apparatus, methods and computer program products for locating unmanned aerial vehicles (UAVs). A region of airspace may be scanned with two scanning apparatuses. Each scanning apparatus may include one or more directional Radio Frequency (RF) antennae. The two scanning apparatuses may have different locations. Radio frequency signals emitted by a UAV can be received at each of the two scanning apparatuses. The received radio frequency signals can be processed to determine a first location of the UAV.
Claims20
A method for tracking unmanned aerial vehicles (UAVs), the method comprising:
- scanning a region of airspace with two scanning apparatuses, each scanning apparatus comprising one or more directional Radio Frequency (RF) antennae, the two scanning apparatuses having different locations;
- receiving first radio frequency signals emitted by a first UAV at each of the two 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;
- receiving second radio frequency signals emitted by a second UAV at a first one of the two scanning apparatuses;
- and
- tracking both the first UAV and the second UAV.
A system for tracking UAVs, the system comprising:
- a plurality of ground data terminals, each ground data terminal 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, each ground data terminal 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 ground data terminals and the corresponding UAV;
- one or more processors in communication with each of the ground data terminals, the one or more processors operable to:
- receive data from at least two of the plurality of ground data terminals;
- process, using locations of the at least two ground data terminals, the data from the at least two ground data terminals determine locations of a first UAV and a second UAV;
- track both the UAV and the second UAV.
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 a region of airspace with two scanning apparatuses, each scanning apparatus comprising one or more directional Radio Frequency (RF) antennae, the two scanning apparatuses having different locations;
- processing first radio frequency signals emitted by a first UAV at each of the two 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;
- processing second radio frequency signals emitted by a second UAV at a first one of the two scanning apparatuses;
- and
- tracking both the first UAV and the second UAV.
