Journal: ELECTRONIC MEASUREMENT TECHNOLOGY

Keyword:  空中目标红外辐射仿真;
Abstract: 本文跟踪了国内外对空中目标红外辐射计算机仿真技术的研究成果,并在掌握与辐射模型相关的计算机图形学、空气动力学与传热学、辐射光学知识的基础上,改进了计算流程和部分算法,完成了目标对太阳、云层、大地的反射和目标表面辐射的建模计算,综合了背景和光源的红外辐射和成像计算的方法,实现了任意观测角度下1~20 μm波长范围内的总辐射和光谱辐射亮度、单个光源辐射强度及背景辐射的计算,得到空中目标的红外图像和辐射数值计算结果,分析了谱段和观测方位对红外热辐射的影响.
