Claim Text:
1. A scene correlation-based target system, comprising: a first camera operable in a first electromagnetic spectrum and a second camera operable in a second electromagnetic spectrum different than the first electromagnetic spectrum, the first camera located at a first position and the second camera located a second position different than the first position, and wherein the first and second positions are adjacent combat theater; a target remote from the first and second cameras positioned in an engagement area; a reference image captured by the first camera in the first electromagnetic spectrum at the first position depicting a remotely-positioned reference scene including a contrast differential boundary line matching a profile of the remotely-positioned reference scene, wherein a known reference directional vector is established between the first camera and a remotely-positioned reference object in the reference scene; a first range established from the first camera at the first position to the remotely-positioned reference object; a second range established from the second camera at the second position to the target; a target image captured by the second camera in the second electromagnetic spectrum at the second position and including the target located near a general vicinity of the remotely-positioned reference object having an unknown directional vector between the second camera and the target, the target image having at least a portion of the contrast differential boundary line matching the profile of the remotely-positioned reference scene; an inertial measuring unit having a scene correlation system, wherein the scene correlation system matches the portion of the contrast differential boundary line matching the profile of the remotely-positioned reference scene of the target image with the contrast differential boundary line matching the profile of the remotely-positioned reference scene of the reference image, wherein an angle between the reference image and the target image is calculated; a target image directional vector derived from the calculated angle, and the reference directional vector; and a calculated target location in the engagement area derived from the target image directional vector and the second range.
