摘要
在迄今为止的海面目标红外热像理论建模研究中,都采用了所谓"薄壳"结构模型,并且在计算中都使用了稳态温度场近似[1,2]。该文为不能按薄壳模型处理的船壳结构建立了非稳态温度场的物理模型,该模型继承了已有模型的成熟算法和软件,并对原有的理论公式和软件进行了扩展,作了计算机理论模拟计算,研究了厚壳船体的体效应对目标非稳态温度场分布的影响。
'Thin hull' model has been used in the theoretical simulation researches of infrared images of objects on the sea up to now and static approximation adopted in the calculation. The physical model is developed for those ships which can not be treated as thin hull and the temperature field changes with time. The model established can inherit the mature algorithms and software of the existing models. Through the extension of the theoretical equations and corresponding software of the thin hull model simulation calculations are made and the effects of body structures of a ship with thick deck on the changing temperature fields of the ship's outside surfaces are studied.
