Abstract

A system for correcting the aim of a weapon which is operative to launch a projectile from a barrel on a ballistic path toward a target. A rear surface of the projectile is coated with a fluorescent dye that re-emits radiation when excited by laser radiation. The system includes a source of laser radiation (strobe) pulses that form a cone of light intersecting the ballistic path of the projectile. The strobe pulses are emitted at predetermined times (T1, T2, T3, . . . Tn) following firing of the projectile (at time T0). An optical detector receives the radiation re-emitted by a the fluorescent dye at the rear of the projectile at times (T1z, T2z, T3z, . . . Tnz) producing measurable location signals allowing the system to measure the vertical and lateral positions of the projectile at said times, where “z” is a re-emission delay and T1z, T2z, T3z, . . . Tnz are the respective times T1, T2 , T3, . . . Tn each delayed by amount z.
