增量比例导引弹道仿真研究

通过引入附加增量,对传统的比例导引方法进行改进。建立了增量比例导引方法的数学模型,运用Matlab语言进行仿真计算,分析了不同的比例导引系数、附加增量对导引弹道及导弹与目标相遇时间的影响,得到不同导引系数及附加增量下的弹道曲线和弹目相遇时间,仿真结果表明与传统的比例导引方法相比,在比例导引系数不变的情况下,选择合适的附加增量可以减少导弹与目标的相遇时间。

Missile Trajectory Simulation Based on Increment Proportional Guide

This paper introduces the additive increments to improve the traditional proportional guide method, establishes the math model of increment proportional guide method, and using Matlab language to simulate it, then it analyzes different proportional guide coefficient and additive increment that effect guide trajectory and encountering time of missile and target, and gets different missile trajectory curves and encountering time of missile and target. The simulation results indicate that under the same proportional guide coefficient, compared with traditional proportion guide method, choosing right additive increment can reduce encountering time of missile and target.
