红外成像靶船辐射特性模拟设计

Simulation Design of Radiation Characteristics of Infrared Imaging Target Ship

针对采用典型舰船实测分析与理论计算相结合的方法,通过对舰船烟囱和动力舱等关键部位红外辐射特性进行研究,构建典型舰船红外辐射分布几何模型。利用水平投影和网格划分方法,对典型舰船目标红外辐射面积和辐射温度空间分布特性进行量化提取,完成模拟典型舰船目标形状和红外特性靶体的设计。与实船对比测试结果表明,该设计实现了对模拟靶船逼真程度评估。

The infrared radiation characteristics of the key parts of the ship, such as funnel and power cabin, are studied by using the method of combining the measurement analysis and theoretical calculation of the typical ship, and the geometric model of the typical ship infrared radiation distribution is constructed. The spatial distribution characteristics of infrared radiation area and radiation temperature of typical ship targets are quantitatively extracted by using horizontal projection and grid division methods, and the design of target body simulating the shape and infrared characteristics of typical ship targets is completed. Compared with the real ship, the test results show that the design realizes the realistic evaluation of the simulated target ship.
