Systems and methods of non-line-of-sight passive detection and integrated early warning of an unmanned aerial system by a plurality of acoustic sensors are described. In some embodiments, the plurality of acoustic sensors is positioned within an intra-netted array in depth according to at least one of a terrain, terrain features, or man-made objects or structures. The acoustic sensors are capable of detecting and tracking unmanned aerial systems in non-line-of-sight environments. In some embodiments, the acoustic sensors may be in communication with internal electro-optical components or other external sensors, with orthogonal signal data then transmitted to remote observation stations for correlation, threat determination and if required, mitigation. The unmanned aerial systems may be classified by type and a threat level associated with the unmanned aerial system may be determined.

Acoustic detection of small unmanned aircraft systems

A method and apparatus for automatically forming and filling sandbags. The apparatus has an excavator for obtaining fill material for the sandbags. The fill is transported from the excavating means to a hopper which dispenses the proper amount of fill into a bag. The bag is formed from two webs of bag forming material which are joined along their edges to form a tube. A clamping, cutting and stitching mechanism clamps and cuts the tube, forming the tops and bottoms of the sandbags. A stitching mechanism stitches the cut top and bottom. The clamping, cutting and stitching mechanism is operated by a hydraulic piston which pulls the sandbag web material from rolls and moves the web from the filling area to the discharge area. A conveyor system moves the formed sandbags from the device for stacking or use. The entire apparatus is mounted on a tractor-type frame so that it can be transported from one location to another.
