摘要
本文基于中段空间实验红外天文星表(MSX-IRAC),建立了星空点源背景可见光与红外辐射场景生成模型。通过位置计算得到星表内恒星在当前观测视场内的坐标,分别采用直接处理星表记录的辐射计值和光谱模板技术两种方法计算视场内恒星的辐射量,不仅可仿真星表记录的谱段场景,还可仿真从紫外到红外(0.115~35μm)任意谱段的场景。
In this work,a visible and infrared radiation scene generation model of celestial point source background was developed based on midcourse space experiment infrared astronomic catalog(MSX-IRAC).The stellar coordinates in current field of view(FOV) were generated by calculating stellar position in the catalog.The radiation of each star in the FOV is calculated by two methods.One is direct processing of photometry in catalog,another is spectral template technique.The model can simulate not only the scene of bands recorded in the catalog,but that of any band from ultraviolet to infrared in the range of 0.115-35 μm.
