All-optical precision gunnery simulation (PGS) method and system

An all-optical precision gunnery simulation (PGS) system that may be adapted to simulate many tactical gunnery scenarios. The eye-safe system of this invention uses a 1550 nanometer optical infrared (IR) signal to permit increased range and field-of-view (FOV) and reduced scintillation over that of the 904 nanometer IR signals known in the art. Temporal and spatial diversity permit error-free operation over long ranges through dust and scintillation. The system performs all trajectory simulation and hit-miss assessment at the target, thereby permitting the shooter to "fire and forget" without holding station to monitor the target position. The simulation results may be reported to the shooter by passively modulating the retroreflection of an optical return window signal from the shooter. Alternatively, the target may compute shooter position from incoming optical pixel signal data for use in reporting by means of an active narrow-beam optical signal from the target back to the shooter.
