A combined net structure is disclosed that comprises a non-planar coarse net with a grid-like structure comprising a plurality of coarse cables wherein longitudinal coarse cables intersect with latitudinal coarse cables to form a plurality of coarse cells and cutouts of a fine net attached to the coarse net, wherein the fine net comprises a plurality of adjacent fine cables. Each non-edge fine cable is attached to two adjacent fine cables on each of its sides at a plurality of locations along their lengths forming attachment points, wherein the fine net is arranged in a form of an array of fine quadrangular cells with said attachment points constituting the vertices of the fine quadrangular cells. System that comprises the combined net structures are disclosed as well.

A drone disabling device includes a plurality of streamer launch tubes having at least one streamer device positioned therein. A barrel housing is configured to hold the plurality of launch tubes within streamer launch barrels. An ignition system is configured to ignite propellant within the launch tubes and launch the streamer devices from the barrel housing such that one or more propellers of a hostile drone will become entangled and disabled. A parachute connected to the streamer device is deployed as the drone descends to protect people and property on the ground and to preserve the drone for intelligence gathering after landing.

The invention provides a system and method for intercepting a target UAV by releasing a plurality of countermeasure (CM) objects in a projected path thereof to form a 3D countermeasure cloud. Pieces of flexible materials configured to become ensnared in the propellers of the target UAV or otherwise interfere with their ability to provide lift and thrust capabilities to the UAV. A UAV interception control system may track the target UAV and compute a location probability volume therefor using a modified Kalman filter to decide on a projected interception location and time.

An integrated airspace defense system for identifying and locating a suspicious unmanned aerial vehicle. The system including at least one detection device to monitor the air space and provide a detection information; a computer to process the detection information and identifying the presence of suspicious unmanned aerial vehicles (UAVs) using a sequence of detection algorithms. The integrated airspace defense system identifies and locates the suspicious UAV. In at least one embodiment the integrated airspace defense system is capable of capturing or destroying the suspicious UAV.
