【摘要】 利用目标的红外辐射特性进行目标探测和识别是一种有效的方法。以某航天器为研究对象,应用节点网络法建立了热分析理论模型,利用ThermalDesktop建立了热分析数值仿真模型,调用Sinda/Fluint求得温度分布信息,最后利用普朗克定律对其红外辐射分布进行了数值计算。仿真解决了空间目标红外辐射的计算问题,为复杂空间目标红外辐射特性的工程计算提供了有利支持。更多还原

【Abstract】 Making use of the infrared radiation property of a moving target is an effective method for target detection and identification.A certain type of space vehicle was chosen for study.The method of node network was applied to theorize thermal analysis,and Thermal Desktop software was used to establish the numerical model for thermal analytical simulation.Then Sinda/Fluint software was called to get the information of temperature distribution,and the numerical calculation of the target infrared heat radiation distribution was finally executed standing by the Plank principle.The simulation results showed the validity of the theory,and provided strong support to complex space target infrared radiation analysis.更多还原
