| 摘 要： | 设计并制作了14个不同几何特征参数的V-型铝箔皱褶构型板。运用电磁数值仿真软件对它们的雷达散射截面(RCS)进行了计算，分析了V-型皱褶板几何特征参数对雷达散射性能的影响。同时，用LFY铝箔制作了14个不同几何特征参数的皱褶构型板，并对它们进行了RCS实验测试。通过对比分析发现，数值计算结果和实验测试结果基本吻合。结果显示，在一定的结构参数下，轻质铝箔皱褶板的RCS比同样平面几何尺寸的平板小，有的甚至降低20 dBsm。铝箔皱褶板成型工艺简单，结构重量轻，价格低廉，可用于包敷飞行器内部有较大RCS的大尺寸构件，从而降低整个飞行器的RCS。

| Abstract: | The fourteen different plates with folded structure made of aluminium foil are designed; their radar cross section (RCS) is calculated using the electromagnetic numerical simulation software. The effect of geometric parameters on the RCS of the plates is investigated. The specimens of the fourteen different plates with different geometry are made from LFY aluminium foil. The RCS experiments of the plates are carried out in the anechoic chamber. The comparisons of experimental and simulation results indicate... |
