海战场环境下超音速反舰导弹红外辐射特性研究

Infrared radiation characteristics of supersonic anti-ship missiles in sea battlefield environment

超音速反舰导弹的红外辐射特性研究对海战攻守双方都具有重要的参考价值。对海洋战场环境红外辐射特性进行了深入分析,引入了累积因子,在考虑了粒子的多次散射效应的基础上建立了仿真环境的辐射计算模型,重点对云层的辐射进行了计算,并通过仿真,验证了模型的可行性。建立了导弹蒙皮与尾焰的红外辐射特性和辐射面积的计算模型,对导弹的红外辐射亮度和辐射强度进行了仿真计算。最后对仿真结果进行对比分析,结果表明该算法能够有效地应用于粒子系统的辐射计算,可供后期生成红外图像序列使用。

The supersonic anti-ship missile infrared radiation characteristic research has the important reference value to naval battle offense and defense both sides. Provided an in-depth analysis of the infrared radiation characteristics in sea battlefield environment, introduced cumulative factor, the environment radiation computation model was established in view of the multiple scattering effects of particle, Focus on cloud radiation calculations, the model feasibility had been confirmed by simulation. Established the computation model of the IR radiation characteristics and radiating area of missile skin and plume, carded on the simulation computation to the missile infrared radiation brightness and the radiation intensity. Finally, by comparison and analysis of the simulation results, the result indicates that this algorithm can be applied in the radiation calculation of particle system effectively, can be used for generation infrared image sequences.
