强光干扰高温稀疏体系辐射能量计算方法研究

强光干扰辐射能量是强光干扰源设计的关键参数，干扰效果一般依托于辐射能量的大小。在假设强光干扰燃烧产物为稀疏体系的前提下，提出一种强光干扰辐射能量计算方法。该方法稀疏体系在空间上进行分层，体系内每个金属氧化物颗粒作为灰体辐射源，对颗粒的辐射能量进行计算，并考虑各层间的热量传递以及体系内金属燃烧化学反应，统计从体系表面出射的辐射力，得到体系的辐射能量。以Al和KClO₄作为燃烧剂对提出的计算方法进行了仿真验证，仿真结果与文献［1］中实验结果良好吻合。提出的辐射能量计算方法可为强光干扰源及红外诱饵弹等辐射问题的研究提供参考。

Research on Calculating Method of Strong Light Interference High Temperature Radiation Energy Sparse System

Light interference radiation energy is a key parameter to design a light interference source, and the interference effect depends on the size of radiation energy. Under the assumption of a high-heat combustion product being sparse, a method to calculate strong light interference radiation energy is proposed. The sparse system is layered in space. Each metal oxide particle is regarded as a grey body radiation source, the radiation energy from particles and the exchanged heat between different layers are calculated, and the emitted light from the surface of system is counted. Al and KClO₄ are used as fuel to verify the proposed calculating method. The results show that the proposed calculating method can be used to calculate the radiation energy from strong light interference source and infrared decoy bomb.
