Abstract

A system for precisely calibrating the misalignment of a weapon-mounted zeroed small arms transmitter (ZSAT) laser beam axis with the shooter line-of-sight (LOS) to a target in a weapon training system. When a blank cartridge is fired through a blank fire adapter (BFA) affixed to the weapon muzzle in a predetermined disposition, the dynamic muzzle displacement during the first milliseconds may be characterized as a two-dimensional shooter-independent 'signature' representative of the BFA disposition, the blank cartridge and the weapon. The misalignment of the ZSAT laser beam axis with the shooter LOS is calibrated by transmitting a sequence of optical pixel signals during an early portion of the dynamic muzzle displacement interval to paint a target. A shooter LOS offset is deduced from the number of pixel signals illuminating the target and stored to compensate for any misalignment of the ZSAT laser beam axis with the shooter LOS during later use.
