More Information
Summary:The invention discloses a dynamic time-domain spectrum fitting method based on a solar elevation angle, which comprises the following steps: calculating the solar elevation angle h of a selected place, date and time period in a set area, calculating an equivalent atmospheric path L'corresponding to the solar elevation angle h, obtaining atmospheric mass m (m = L '/L), and calculating an atmospheric pressure relational expression corresponding to the atmospheric mass m and the altitude H; and performing dynamic fitting on solar radiation in a visible light wave band, establishing a solar dynamic spectrum model, obtaining an average spectrum function, and obtaining a fitting spectrum under any atmosphere mass m condition. According to the dynamic time-domain spectrum fitting method based on the solar elevation angle, sunlight colors under any longitude and latitude, any time and any altitude condition are clearly simulated theoretically, and dynamic sunlight in a clear sky, cloudless and clean air environment i
