海面物体热像模拟的通用物理模型研究

Research on General Physical Model for Simulation of Infrared Image of Sea Object

在通用的海面物体三维几何构型的描述以及准均匀网格生成方法的基础上,改进了原有的海面物体热像模拟物理模型,建立了通用的海面物体热像模拟物理模型,并进行了计算机实现,计算结果表明该通用物理模型涵盖了原有的物理模型,并使有些计算结果的精度得到了提高,还可进一步扩展后应用到其它环境下物体的红外辐射场的模拟。

Based on the general three dimensional description method of geometrical model of objects and the corresponding generating principle in light of semi-uniformed element division method, the physical model for the simulation of sea object infrared images which was developed earlier was improved and a more generic model developed with software to use the model was established. Calculation results prove that the new model is more universal than the previous ones and the latter can be taken as special cases of the former. The new model can improve the precision of some result and it can be used to simulate infrared radiation fields of object in other environment after a little modification.
