弹头壁面温度场建模及红外辐射特性研究
Modeling of missile wall temperature field and its infrared radiation characteristics
摘要
Abstract
Space target infrared signal is hard to measure actually, and obtained mainly by simulation. This paper establishes the wall temperature field model of target in midcourse, choosing warhead and two sorts of decoys as simulation objects, and obtains the surface average temperature and its changing law of radiation degree, by considering the impact of surface material and its internal heat source on the warhead and using the finite volume method to solve the distribution of wall temperature field. The distribution of target’s radiation spectrum is computed by further analyzing the target’s reflection on the environmental radiation. By simulation analysis it can be seen the diversity among the surface temperature distribution between the warhead and decoys, changing rate of the radiation degree, and the spectrum distribution, thus offering the basic parameters and theoretical basis for infrared detection and identification.关键词
