红外波段可探测到足够多用以导航的星体。受限于客观条件，白天无法获取大量的星空图像。为了加快三视场恒星检测、星点定位和星图识别等算法的开发及算法性能的全面测试，需要研究三视场全天时星图的仿真方法。研究并建立了三视场天空辐射模型、系统噪声模型和恒星成像模型，设计并运行了三视场星图的生成软件。结果对加快算法的开发及算法性能的全面测试具有重要意义。

Enough stars for navigation can be detected at infrared wavelengths. Limited by the objective conditions, large quantity of star images can not be obtained in the daytime. To accelerate the development and performance testing of the algorithms for three field-of-view star detection, star point location and star pattern recognition, a method for simulating all-time three field-of-view star images should be studied. The models of three field-of-view sky radiation, system noise and starimaging are established. The software for generating three field-of-view star maps is designed and operated. The result obtained is of importance to the acceleration of development and full performance testing of related algorithms.
