Abstract
A system, method, and non-transitory computer readable medium that detects trajectories of unmanned aerial vehicles (UAV) approaching a protected site is described. Airborne defense agents (ADAs) located at a fixed radius from the protected and equidistant from one another detect acoustic signals emitted by an approaching UAV. Circuitry included in each ADA use the detected acoustic signals to determine a direction and a distance of each UAV. A base station having a control center (BS-CC) located in the protected site communicates with the ADAs to aggregate direction and distance data from the ADAs. Using the aggregated direction and distance data, the BS-CC predicts routes towards the protected site of the approaching UAV and alerts the protected site of the predicted route of the approaching UAV.
