地面照度

矢量法在计算空间目标地面照度中的应用

Application of vector method to the calculation of space target ground irradiance

从基本辐射理论出发，推导了空间漫反射目标地面照度的计算公式，详细讲解了采用矢量法对该公式中的积分进行计算的过程。

Starting from the basic radiation theory , the calculation formulae for ground irradiance of space scattered reflection target are derived . The calculation process for integration in the formulae with vector method is explained in detailed .

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。

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 .
