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 detecting unmanned aerial vehicles (UAVs) in a sensitive security area, the method comprising:
- scanning, with a plurality of scanning apparatuses, a region of airspace associated with the sensitive security area, each scanning apparatus comprising one or more Radio Frequency (RF) antennae configured to receive a variable amount of radio wave power, the variable amount of radio wave power received by each RF antenna being configured to vary based on an angle between a propagation direction of the received radio wave power and an axis of the antennae, each of the scanning apparatuses having different locations, at least one of the scanning apparatuses being connected with a moveable vehicle;
- receiving 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, the first radio frequency signals being downlink signals generated by the first UAV to communicate with a first device controlling the first UAV, the scanning apparatuses being independent from generation of the first radio frequency signals;
- processing, based on a signal strength of the first radio frequency signals at the scanning apparatuses and a relative position of the scanning apparatuses with respect to the signal strength of the first radio frequency signals, the first radio frequency signals to determine a first location of the first UAV;
- and
- automatically causing the first UAV to be automatically shot down.

A system comprising a plurality of scanning apparatuses coupled with one or more processors, the system configured to cause:
- scanning, with the plurality of scanning apparatuses, a region of airspace associated with the sensitive security area, each scanning apparatus comprising one or more Radio Frequency (RF) antennae configured to receive a variable amount of radio wave power, the variable amount of radio wave power received by each RF antenna being configured to vary based on an angle between a propagation direction of the received radio wave power and an axis of the antennae, each of the scanning apparatuses having different locations, at least one of the scanning apparatuses being connected with a moveable vehicle;
- receiving 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, the first radio frequency signals being downlink signals generated by the first UAV to communicate with a first device controlling the first UAV, the scanning apparatuses being independent from generation of the first radio frequency signals;
- processing, based on a signal strength of the first radio frequency signals at the scanning apparatuses and a relative position of the scanning apparatuses with respect to the signal strength of the first radio frequency signals, the first radio frequency signals to determine a first location of the first UAV;
- and
- automatically causing the first UAV to be automatically shot down.

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 the plurality of scanning apparatuses, a region of airspace associated with the sensitive security area, each scanning apparatus comprising one or more Radio Frequency (RF) antennae configured to receive a variable amount of radio wave power, the variable amount of radio wave power received by each RF antenna being configured to vary based on an angle between a propagation direction of the received radio wave power and an axis of the antennae, each of the scanning apparatuses having different locations, at least one of the scanning apparatuses being connected with a moveable vehicle;
- receiving 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, the first radio frequency signals being downlink signals generated by the first UAV to communicate with a first device controlling the first UAV, the scanning apparatuses being independent from generation of the first radio frequency signals;
- processing, based on a signal strength of the first radio frequency signals at the scanning apparatuses and a relative position of the scanning apparatuses with respect to the signal strength of the first radio frequency signals, the first radio frequency signals to determine a first location of the first UAV;
- and
- automatically causing the first UAV to be automatically shot down.
