1. A non-transitory storage device operatively coupled to at least one processor of a multi-sensor detection system, the non-transitory storage device configured to store unmanned aerial vehicle target information comprising: radar data comprising three-dimensional X, Y and Z location coordinates indicating tracked target positions of an unmanned aerial vehicle; radio frequency receiver data indicating a target radio frequency spectral signature of the unmanned aerial vehicle; radio frequency directional antenna alignment data indicating azimuth and elevation vector coordinates of relative target positions of the unmanned aerial vehicle; Laser Range Finder data indicating target range and bearing of the unmanned aerial vehicle; and optical image data indicating target shape/profile of the unmanned aerial vehicle; the radar data, the radio frequency receiver data, the radio frequency directional antenna alignment data, the Laser Range Finder tracking data and the optical image data being configured to enable the processor to compute a threat assessment value for the unmanned aerial vehicle based on combining at least three or more of the target location coordinates, target classification, the bearing, target speed, identified payload, target shape/profile, and tracked target flight profile.
