APPARATUS FOR CORRECTING BALLISTIC ERRORS USING LASER INDUCED FLUORESCENT (STROBE) TRACERS

摘要

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, Τ3,...Τn) 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,...Τnz) 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,...Τnz, are the respective times T1, T2, Τ3,...Τn each delayed by amount z.
