Genetic Programming Based Model Structure Identification Using On-Line System Data

A projectile trajectory correction system, the projectile itself including a unique steering arrangement. The projectile, initially part of a shell cartridge, is fired, and its position is automatically sensed. A corrected trajectory necessary to hit a target is calculated and data commands are transmitted to the projectile. The data command signals are sensed by an antenna on the projectile. The antenna in turn generates a signal which is fed to the projectile steering mechanism which is deflected in response thereto to steer the projectile onto the correct trajectory. The steering mechanism includes an elongated rod extending from the rear of the projectile into the surrounding air stream. Deflection of the rod provides the actual steering.
