【摘要】 由于制造工艺的原因,天线罩介质材料的物性参数存在随机误差,会对系统电性能产生影响。针对介质夹层式天线罩中影响电性能的两种主要物性参数相对介电常数和损耗角正切,建立其随机误差对电性能影响的分析模型,利用某工程的9.14m天线罩进行仿真实验,分析了某种程度的罩体材料随机误差下对应的具体电性能指标。研究结果表明,材料物性参数的随机误差对系统电性能的影响显著,且芯层材料随机误差的影响远大于蒙皮材料,相对介电常数随机误差的影响远大于损耗角正切。更多还原

【Abstract】 In the manufacturing process,random error is introduced in the material properties of radome which affects the electrical performance.The effect of two main material properties that affect electrical performance,dielectric constant and tangential loss,is analyzed by establishing the analysis model between their random error and the electrical performance.A simulation of some 9.14 m radome with random error of certain degree shows that random error of material properties greatly affects the electrical performance.Further analysis indicates that the effect of random error of core layer material is considerably greater than that of skin material,while the effect of random error of dielectric constant is considerably greater than that of tangential loss.更多还原
