基于欧拉法的自寻的炮射导弹弹道建模与仿真

Modeling and Simulation of Self-Homing Gun-Launched Missile Trajectory Based on Euler Method

摘要:

根据炮射导弹“自寻的”的发展趋势,大多数炮射导弹基本都采用激光架束制导、半主动自寻的模式。由于其自身局限性,随着主战坦克的装甲防护性能提高,激光架束制导的炮射导弹无法达到理想的毁伤效果。文章以某型炮射导弹作为参考原型,提出了新一代“自寻的”炮射导弹的“攻顶”弹道模型。弹道模型可以避实就虚,“攻顶”攻击坦克的薄弱部分,尽可能发挥炮射导弹的战斗效能。在外弹道学和导弹总体参数的基础上,建立导弹从炮口发射到比例导引段毁伤的运动方程,利用欧拉法求解弹道方程组,并用 Matlab编程进行仿真。仿真结果表明,炮射导弹可以实现攻顶弹道,为未来实现炮射导弹智能化提供借鉴。

Abstract:

According to the development trend of“self-homing”of gun-launched missiles, most gun-launched missiles ba?sically adopt the laser frame beam guidance and semi-active self-homing mode. Because of its own limitation, with the im?provement of armor protection performance of main battle tank, the gun-launched missile guided by laser frame beam can?not achieve the ideal damage effect. Taking a certain type of gun-launched missile as a reference prototype, a new genera?tion of“self-homing”gun-launched missile“top attack”trajectory model is proposed in this paper. The“top attack”bal? listic model can evade the reality, attack the weak part of the tank, and maximize the combat effectiveness of gun-launched missiles. On the basis of outer ballistics and overall parameters of the missile, the motion equation of the missilefrom the muzzle launch to the damage of the proportional guidance section is established. The simulation results showedthat the gun-launched missile can achieved the top trajectory, which provided a reference for the realization of intelligentgun-launched missiles in the future.
