雷达关键部件对西北地区典型环境适应性的综合仿真研究

摘要

长期工作在西北地区大温差、多风砂和强紫外线等恶劣复杂环境下的雷达装备表面极易出现表面磨蚀或损坏。建立了雷达对西北地区综合环境适应性的仿真分析方法，以计算流体动力学（CFD）软件FLUENT为平台，对雷达典型部件在大温差、多风砂和强紫外线环境中的表面状态进行仿真模拟。仿真结果与雷达装备实际情况较为吻合，为进一步深入研究相关物理机理以及设计防护措施提供了理论依据。%Radar equipment are prone to surface abrasion or damage for a long-term working in the bad complex northwest region of in the large temperature difference and multi wind sand and strong ultraviolet. In this paper, a simulation analysis method of radar to the comprehensive environmental adaptability of the northwest area is established. Based on the computational fluid dynamics (CFD) software FLUENT, the simulation of the surface state of radar typical components in the large temperature difference, multi wind sand and strong ultraviolet environment is simulated. The simulation results are consistent with the actual situation of radar equipment, which provides a theoretical basis for further study of the physical mechanism and design of protective measures.
