| 摘 要： | 从辐射理论出发,对太阳可见光波段大气层外辐照度理论值进行了1/1.07倍的修正,推导出构成卫星的两种基本漫反射表面的地面照度计算公式,再由太阳、卫星和观测站在地心赤道坐标系中的位置矢量关系,算出它们的具体值。理论计算表明,虽然太阳能帆板的漫反射率要比卫星主体低30倍,但在卫星地面照度的计算和实际观测中仍不应忽略。

| Abstract: | Based on radiation theory, a correction with 1/0.7 times of theoretical value of solar irradiance in visible band outside atmospheric layer is carried out, thus ground irradiance calculation formulae of the two basic diffuse reflection surfaces of satellites are derived. Their practical values can be calculated from the relative position vector relations of sun, satellite and observation station in equatorial coordinate system. Theoretical calculation shows that the diffuse reflection index of solar battery panels is 30 times lower than that of main satellite body, but it still cannot be ignored in calculation of ground irradiance of satellite and practical observations. |
