Method and precision analysis of the trajectory identification of range correction fuze

The method and precision of trajectory identification of a range correction fuze based on projectile of compound extended range by base bleed and rocket were studied. Based on the theory of Monte-Carlo simulation, the trajectory wind, initial velocity and trajectory coefficient were taken as the initial parameters in order to formulate the random probability model, by which random trajectory was computed. According to the real acceleration value, the calculated trajectory was identified by the trajectory identification algorithm. The precision of the trajectory identification method were obtained by comparing the ranges of the identified trajectory with the calculated trajectory. The result shows that the error of the trajectory identification algorithm is less than 1%, and the precision can meet engineering request.
