Abstract

A drone defense system (DDS) beacon detects unmanned aerial systems (UAS) traffic and transmits a broadcast signal over a transmission region indicating a no-fly zone in which only UAS having an authorization are allowed to fly. The beacon allows UAS with clearance to enter the no-fly zone. Those UAS without clearance are diverted around the no-fly zone, denied Wi-Fi and/or RF connection, forced to return to home launch sites via activation of standard preprogrammed Return to Home (RTH) routines, or forced to land at specified locations where they may be captured. Military, emergency medical services (EMS), and other UAS are allowed to enter no-fly zones in which other UAS, such as commercial, or consumer UAS, cannot enter. DDS cloud collects and stores log data from all deployed DDS beacons. DDS cloud can send system software updates to DDS beacons, make real-time statistical analysis, and provide report data to outside systems.

Claims

1. A method of detecting an unnamed aerial system (UAS), the method comprising the steps of:

detecting, via a transceiver, a signal stream, wherein the signal stream contains one or more wireless transmissions from one or more sources, and wherein the signal stream includes one or more communications between the one or more sources;

filtering, via a processor, the signal stream to create a filtered stream; and

classifying, via the processor, the filtered stream based on features associated with the filtered stream as a known UAS stream or a potential UAS or other wireless communications stream or a combination thereof, wherein the features include a periodic time, a dwell time, a power, a modulation type, and a channel space associated with the filtered stream.

2. The method of claim 1, wherein if the known stream matches at least one previously obtained signal stream, and wherein the potential UAS stream is compared to a number of criteria in order to verify the signal is an unknown UAS stream.

3. The method of claim 1 further comprising the step of:

tracking, via the processor, the known stream of the UAS, wherein the tracking is performed by mapping at least a portion of a hopping sequence attributable to the UAS.

4. The method of claim 1 further comprising the step of:

executing, via the processor, at least one command causing a response in the UAS.
