脉冲末修弹落点预测导引方法研究

Research on Impact Point Prediction Guidance Method of Pulse Terminal Trajectory Correction Projectile

在分析剩余射程影响因素的基础上,以弹道特征参数弹道高y及速度矢量分量Vx和Vy为解释变量,以回归分析方法为数学工具,建立脉冲末修弹剩余射程预测模型。以目标点与弹丸预测落点之间的差值为广义弹道偏差,结合数值仿真,对落点预测导引进行深入研究,验证了回归分析模型的可行性。

On the basis of analysing the effect factors of residual range and using the trajectory characteristic parameters including trajectory highness y、velocity vector Vx and Vy as independent variable,the residual range model of pulse jets terminal trajectory correction projectile is set up by using regression analysis method.Based on the general trajectory error of the distance between the target point and the precdition impact point,combined with the numerical simulation model,the impact point prediction guidance mode is studied,and the regression analysis model is feasible.
