摘　　要：红外诱饵弹是一种常见的红外干扰武器,能够对红外制导武器产生很强的干扰效果。在众多类型的红外诱饵弹中,通过投放药剂形成喷射火焰来得到干扰辐射源的方法仍在实战中广泛应用。在这类诱饵弹的研发制造过程中,投放药剂的半径对诱饵弹辐射特性具有很大的影响。针对药剂颗粒半径对诱饵弹辐射特性的影响,分析了典型的投放药剂类红外诱饵弹的结构及工作原理,借助了离散相模型(DPM模型)对红外诱饵弹红外特性建模,总结了典型诱饵弹模型下的红外诱饵药剂颗粒直径与辐射特性间的关系,最后通过最小二乘法对仿真数据进行拟合后确定该典型红外诱饵弹辐射强度最大时的药剂颗粒半径为3.72 mm。该方法对诱饵弹投射颗粒半径的研究工作提出了依据,在诱饵弹研发与仿真中具有重要的指导价值。Infrared decoy is a common infrared countermeasures weapon, which has a significant jamming effect on infrared-guided weapons. Among many kinds of infrared decoys, the method of releasing some composition to generate a jamming radiation source is still widely used in practice. In the development and manufacturing process of this kind of decoy, the particle radius of composition has a great influence on decoy＇s radiation characteristics. To study the influence of the particle radius of composition, in this paper,the structure and working principle of infrared decoy were analyzed, the infrared characteristic model of decoy based on discrete phase model（DPM model） was built, the relationship between particle radius of infrared decoy and radiation characteristics was summarized. Finally, through fitting simulation data base on the least square method, the optimal particle radius of 3.72 mm was found while infrared decoy had maximum radiation intensity. This method lays a research foundation for the particle radius of composition of infrared decoy, and also has great guiding value in the field of decoy＇s research and simulation.
