红外诱饵弹投放装置控制参数研究

Operational parameters of airborne infrared decoy aerial-lauched set

红外诱饵弹是作战飞机最常用的一种干扰,它对红外制导空空导弹的干扰效果与投放装置的控制参数密切相关,通过深入研究空战时的红外对抗过程,确定了红外诱饵弹投放装置的主要控制参数。在研究自卫飞机、红外诱饵弹和红外制导导弹的运动特性和红外辐射特征基础上,分析了红外诱饵弹质心干扰原理,建立了红外诱饵弹开始投放及停止投放时间、诱饵弹序列投放时间间隔和齐投数量等投放装置控制参数模型,利用该模型计算了典型条件下诱饵弹投放控制参数与干扰效果的关系,该模型对提高诱饵弹的干扰效率,保护自卫飞机安全具有一定的指导作用。

IR decoy is one of the most common interferences for battleplane. The effect of IR decoy on the IR guidance air-to-air missile was closely related to control parameters of aerial-launched set. The main control parameters of aerial-launched set were determined by studying the process of IR countermeasure. The principle of centroid countermeasure of IR decoy was analyzed based on studying the characteristics of movement and IR radiation of self-defence plane , IR decoy and IR guidance missile. Control parameters model of aerial-launched set was built, including start and stop time of aerial-launched set, spacing of sequence aerial-launched decoy and dispensing number. The relationship between control parameters of aerial-launched set and interference effect was calculated. The test results prove that the model can improve the interference efficiency, and protect the self-defence plane.
