A Trajectory Design Methodfor Pulse Correction Projectiles
Due to the limited number of ignition corrections,the trajectory design must be carried out reasonably to achieve the best combat effect for pulse correction projectiles.Aiming at the problem of the trajectory design of pulse correction projectiles for anti-aircraft artillery,an optimization method based on the genetic algorithm is proposed.In this method,the firing timing sequence of pulse correc-tion projectiles is taken as the optimization variable,and the position deviation between the actual tra-jectory and the target future point when the projectile is exploding is taken as the optimization target.An optimization problem is established accordingly to be solved.Taking the deviated trajectory caused by elevation and azimuth angle deviations as the actual trajectory,trajectory design simulations are car-ried out to validate the trajectory design of pulse correction projectiles with different correction capabili-ties.Simulation results show that the trajectory design method is effective.By solving the ignition time sequence of pulse correction projectiles,trajectory schemes with unbiased terminal positions can be ob-tained.The trajectory design method can inform anti-jamming trajectory design considering error terms and the compilation of ignition time sequence tables.
