Abstract

Optical characteristics of sun synchronous orbit satellite FY-1 were studied by simulation and experimental verification in visible and infrared band. Taken as input in calculation of infrared emission, temperature field on satellite surfaces were solved according to the radiation flux of outer sources. Undulating algorithm was used to describe appearance of the surface material. Reflection from satellite was based on judgments of shadow and bi-directional reflectance distribution function (BRDF) of surface materials. The signatures of FY-1 satellite were calculated and analyzed in infrared and visible band. The results show that infrared luminance of satellite surface is related with temperature. The maximum value is 90 W/(m²·sr) in 8~14 μm band, and 20 W/(m²·sr) in 14~16 μm band. The reflected light intensity show remarkable specula reflect. Maximum value is 2200 W/sr. The measurement relative error is less than 20%.
