Abstract:

An exemplary embodiment of the invention relates to determining aimpoint relative to a target located within a firing range. The target can be either fixed or moving, and if the target is moving then it can be mounted on tracks or controlled by servomechanisms. In addition to aimpoint, predicted projectile effects and personnel performance can be calculated for evaluation and for training. The firing range is mapped so that placement of infrared emitters is associated with specific targets. Placement of the emitter external to the target perimeter produces accurate results so long as the emitter is within the field of view of a camera mounted upon the projectile launcher. The invention results in large firing ranges with the ability to place targets wherever desired without decreasing aimpoint measurement accuracy.
