摘要：白天背景輻射以瑞利散射和Mie散射為主，考慮高度、傾斜、方位等因數，建立了白天天空背景的理論模型和計算方法。利用以此算法為基礎的程序進行了模擬計算，得到了0.4～1.1um的天空背景值。將此結果與MORTRAN的計算結果做了比較，兩者吻合較好。該算法簡單，便于實際應用。

Abstract: Ray-leigh scattering and Mie scattering is the main scattering in the day, considering various factors such as height modification, slope distance and azimuth, an integrative theoretic model and the calculation method for the background radiation on day is established. This calculation method for calculating the background of 0.4～1.1um is programmed. The result of this program with the result of the MODTRAN is compared.

Key words: ray-leigh scattering  Mie scattering  background  MODTRAN
