| 摘 要： | 对空间飞行器的电磁波散射截面进行了计算。本文取八种入射频率、五个高度上的电子密度所对应的电磁波散射截面和电声波散射截面进行了计算。结果表明,在正常情况下散射增强范围比Chen在辐射研究中给出的范围要大些。本文还对超高频波段在一些特定区产生的散射增强,用电离层中某些尺寸的不均匀结构的影响给予初步解释。

| Abstract: | Calculations of cross sections of EM and EA waves in 8 different incident frequencies and electron densities "on 5 different elevations have been made. The result shows that under normal circumstances, the scattered EM enhancement is greater than that given by Chen. This enhancement of scattered EM waves under special condition of higher frequencies of special zones may be explained by using the influence of the irregular structure of some size in the ionosphere. |
