影响红外空空导弹地面靶试弹道因素的仿真分析

Simulation and Analysis of Impact Factors on Infrared Air-to-Air Missile Trace in Ground Launch Test

以某红外空空导弹地面靶试试验为背景,通过数字仿真分析了目标辐射特性对导弹抗干扰性能的影响,以及导弹轨上运动、后置离轴角、推力偏心等因素对初始弹道的影响。根据上述影响,给出了合理的导弹发射仰角制定方法,使得导弹初始段和抗干扰过程弹道平稳。地面发射试验的成功证明了该仿真分析的有效性。

Based on ground launch test of an infrared air-to-air missile, the affection of target-radiation on missile anti-jamming is analyzed by digital simulation, then the influence of trace on orbit, postposition offing-axis angle and thrust eccentricity on missile beginning trace are also analyzed. According to these, the method of setting reasonable dispensed pitching-angle is given, and so the beginning trace and the process of anti-jamming are improved. Result of the test proves the validity of digital simulation.
