摘要
Ultraviolet detection has advantages of high sensitivity and low false alarm rate. Analysis of ultraviolet characteristics has great significance for space target detection. An accurate modeling method is proposed for the ultraviolet characteristics of space target. Based on the background environment and material properties of space target, region and grid division are generated, and the mathematical model of ultraviolet characteristics of space target is established by introducing bidirectional reflectance distribution function. The position relations of target, detector and background radiation source are determined by coordinate transformation algorithm. The calculation flow for ultraviolet characteristics of space target is derived. Finally, the observed ranges and irradiation distributions of Ziyuan-1 and Fengyun-3 satellite are calculated by the given parameters. The simulation results demonstrate the validity of the modeling method.
