摘要:

为了研究高温环境对热天线电性能的影响,提出了一种热电联合计算方法,通过三维热、电信息传递程序实现不同温度区域介电性能的空间加载,以此关联温度场与电磁场网格节点信息,实现温度场-电磁场耦合问题的联合计算。介绍了热电联合计算方法的原理与思路,并以某型热天线为研究对象,考查天线温度分布对电性能的影响程度,为飞行器热天线的精细化设计提供了途径。该方法可应用于热透波结构的高温电性能分析,尤其对于恶劣热环境下的热天线/天线罩设计具有较高的应用价值。

Abstract:

To study the influence of high temperature on the electrical properties of thermal antennas, a thermoelectric coupling calculation method is proposed in this paper. The 3D grids information for both temperature field and electromagnetic field are associated by a designed information transfer program, which loads corresponding dielectric parameters based on local temperature to achieve thermoelectric coupling analysis. This paper presents the principle of thermoelectric coupling calculation. To realize fine design of aircraft thermal antenna, the directional patterns of a thermal antenna at room temperature and high temperature are studied and compared. The method can be used to analyze the electrical properties of heat wave-transmitting structure at high temperature, and has an important application in thermal antenna/radome design in harsh thermal environment.

Key words: thermal antennas, radome, thermoelectric coupling, radial basis function, patter
