摘要
机载雷达罩使用过程中容易造成机械损伤,可能会对其电性能发挥产生影响。文中分析了雷达罩常见的机械损伤类型及成因,介绍了雷达罩常见电性能参数,建立了雷达罩蒙皮脱落与线性划伤模型,利用电磁仿真法对不同蒙皮脱落半径和线性划伤长度雷达罩的透波率、天线增益、天线方向图等参数变化进行仿真分析。结果表明,相对于雷达罩实地测试法,所提方法经济实用,天线罩损伤模型有效可行,仿真结论对雷达罩机械损伤对电性能影响评估具有重要的理论指导意义。
The mechanical damage generated in the use process of airborne radome may affect the electrical characteristic of radome. The common types and causes of the mechanical damage of the radome are analyzed. The common electrical performance parameters of the radome are introduced. The radome skin shedding model and linear scratching model are established. The electromagnetic simulation method is used to simulate and analyze the parameters such as wave penetration rate,antenna gain and antenna pattern of radome with different skin shedding radius and linear scratched length. The results show that,relative to the field of radome test method,this method is economical and practical,the radome damage model is effective and feasible,and the simulation conclusions have important theoretical guiding significance for the impact assessment of the radome′s mechanical damage to the electrical performance.
