为了解算红外诱饵弹投放后在红外寻的导弹导引头视场中的分离时间,并分析其变化规律。建立了红外寻的导弹、诱饵弹、目标及导引头锥体视场运动模型,采用VC++语言对诱饵弹脱离导引头视场的过程进行了仿真,设计了6种不同的弹目接近情况,仿真解算出分离时间,归纳出分离时间与目标飞行特性、诱饵弹投放时的弹目相对距离、投放倾角、偏角及导弹攻击方式的关系。仿真结果经过试验验证,误差较小,有较高的工程应用价值。

To calculate separation time of infrared flare in infrared missile seeker's FOV, and analyze the rule of variation, the motion model of infrared missile, infrared flare, target and FOV of seeker cone was established. The process of infrared flare running away from FOV of seeker was simulated by VC++ language. 6 kinds of conditions for missile-target approach were designed. The separation time was calculated, The relations of between separation time and character of flight was concluded, the relative distance between missile and target, dip angle of dropping, and attack mode were given. Simulative result proves that error is small and with high engineering application value.
