基于遗传算法的空空导弹弹道拟合方法

A Method for Approximating Air-to-Air Missile Trajectory Based on Genetic Algorithm

提出了一种基于遗传算法的空空导弹弹道拟合算法。该算法克服了诸如多因变量的多元逐次回归法、单因变量的多元逐次回归法等传统拟合算法的不足。通过对多种型号空空导弹弹道的拟合计算表明该算法可行性好、拟合精度高、拟合模型优化效果好 。

Traditional methods for approximating air to air missile trajectory are unsatisfactory. We have developed an approximating method based on genetic algorithm; the results of this approximating method have been successfully applied to the fire control design of one type of P.R.C fighter aircraft. Section 1 describes the mathematical model of our method. Section 2 explains the five steps of optimizing this mathematical model with genetic algorithm. We have done much numerical simulation. Figs.3 and 4 show only a very small part of the numerical results obtained with our method, which is based on genetic algorithm, for approximating air to air missile trajectory.
