This invention describes a method for operating a weapon targeting system comprising the steps of using a laser to fire a single pulse at a target to obtain a reflected laser pulse; detecting the reflected laser pulse as a signal by a SWIR focal plane; detecting background illumination by using the SWIR focal plane; scene clutter filter and using optical filtering if it is necessary to suppress background illumination.

Laser detection and image fusion system and method

A scene correlation-based target system and related methods are provided. A reference image depicts a remotely-positioned object having identifiable characteristics, wherein a reference directional vector is established relative to the reference image. A target image of a general vicinity of the remotely-positioned object has an unknown directional vector, the target image having at least a portion of the identifiable characteristics. An inertial measuring unit has a scene correlation system, wherein the scene correlation system matches the portion of the identifiable characteristics of the target image with the identifiable characteristics of the reference image, wherein a slew angle between the reference image and the target image is calculated. A target image directional vector is derived from the calculated slew angle and the reference directional vector.
