Research and Simulation Analysis of Impact Point Prediction Algorithm Based on Perturbation Theory
In order to solve the problem of impact point prediction accuracy of one-dimensional modified projectile's external trajectory correction,the perturbation impact point prediction model is improved,and the impact point prediction error is calculated according to the upper and lower perturbation trajectories of relative theoretical trajectory,and the impact point prediction error is averaged.Determine that optimal correction time through the mapping relation between the work range and the correction distance of the off-line resistance mechanism;the Monte Carlo trajectory simulation system is used to verify the trajectory correction effect under various error interference conditions,calculate the statistical parameters of trajectory impact point and evaluate the statistical parameters of impact point,and verify the effectiveness of the improved perturbation model.
