最小告警距离是机载导弹逼近告警的重要指标之一。通过对导弹逼近告警进行条件分析,估算最小告警时间,结合Matlab图形仿真,建立了最小告警距离模型。并且从导引头探测距离的角度着手,对模型进行了进一步修正,最后对建模结果进行了总结。仿真结果表明:该仿真模型符合实际,对后续逼近告警相关研究有很大的参考作用。

The minimum warning distance (MWD) is an important standard of airborne missile approach warning system (AMAWS). Through analysis on the conditions of MAWS and estimation of the MWT, combined with Matlab graphic simulation, the warning distance was modeled, and the model was further modified by seeker ranging analysis, at last the modeling result was summarized. The result of the simulation shows that the threat of frontal attack is the greatest, and it is useful for further study about MAWS.
