摘　　要：针对反坦克导弹采用常规比例导引时存在严重的弹道落角不足的问题,引入弹目视线角和导弹速度矢量前置角反馈,提出了一种适用于俯冲攻击的改进比例导引律,保证了命中点处的落角要求。最后通过仿真验证其弹道特性,并分析了导弹飞行速度和参数测量误差对制导效果的影响。仿真结果表明该导引律在保证了命中精度的同时可以极大的提高击顶落角,而且具有很强的鲁棒性。In order to improve the terminal impact angle of conventional proportional guidance law, a revised proportional guidance law based on the line of sight angle and the velocity vector prepositive angle was proposed in this article to meet the terminal impact angle re- quirement. Finally, some simulations were applied to analyze the character of the trajectory and the influence of missile speed and the measurement error of parameters. The results show that the proposed guidance law can enhance the terminal impact angle greatly with equivalent attack precision of conventional proportional guidance law and has strong robustness.
