Range prediction control method for pulse jet correction projectiles

A trajectory correction scheme based on the directive force of pulse jet was introduced, and the correction guidance law of pulse jet was analyzed. It was pointed out that the longitudinal guidance law is the chief task. The concept of range prediction guidance was brought forward, and the kernel is the foundation of range prediction function, i.e., getting samples by solving ideal trajectory and typical disturbed trajectory, setting up the polynomial model of the range and the intermediate trajectory parameters, and getting the polynomial coefficients by regression. The numerical simulation shows that adopting this correction guidance law, the standard error of the longitudinal falling points of projectiles decrease from 123 m to 21 m.
