| 摘 要： | 基于红外辐射理论，综合考虑自身辐射、反射辐射、大气长波辐射等因素，研究了目标的红外辐射特性仿真方法，编制了目标红外辐射仿真软件。以某钢板为例，建立了目标的仿真计算模型，确定了目标表面的边界条件，计算了目标表面的温度场分布，将仿真计算与试验测量的钢板表面温度数据进行了对比，结果显示:仿真计算的平均误差在1.5 ℃以下，验证了仿真方法的正确性，并在此基础上仿真计算了不同时刻目标的红外辐射特征分布，证明了红外仿真方法的合理性，为车辆与复杂背景的红外仿真计算奠定了基础。

| Abstract: | Based on the infrared radiation theory,some factors such as self-radiation,reflection radiation and long wave radiation of the atmosphere were considered. The simulation method of infrared radiation characteristics of the target and the infrared radiation simulation software of object were studied. With a steel plate as an example, the simulation of the target was modeled, and the surface boundary conditions of object was determined. Through the surface temperature field of the target calculated, the temperature data of the steel plate calculated by simulation was compared with the data measured by test. The results show that the average error of simulating calculation is less than 1.5 ℃, it verifies the correctness of the simulation method. Based on the simulation software, the distribution of infrared radiation characteristics of the target in different time is calculated. The rationality of infrared simulation method is proved, and it lays the foundation of infrared simulation of vehicle and complex background. |
