摘　　要：在卫星构型设计中,要进行视场遮挡分析来判断光学敏感器是否会因为受到卫星其它部件的遮挡而失效.为了取代以往低效的手工分析方法,设计了卫星光学敏感器视场遮挡分析工具.介绍了该工具的设计方法及功能.工具基于三维CAD软件SolidWorks,并以动态链接库(DLL,Dynamic Link Library)的形式与SolidWorks紧密集成.在设计中运用了计算机图形学原理,利用SolidWorks API函数和Visual Basic编程语言进行二次开发.工具能够在SolidWorks中对卫星装配体执行以下敏感器视场遮挡分析功能:定义敏感器视锥特性参数,绘制视场遮挡图和计算视场遮挡率.In satellite configuration design, blinding analysis should be made to determine whether the optical sensor will fail due to being blinded by components of the satellite. A blinding analysis tool for satellite optical sensors was developed to replace the inefficient way of manual analysis. The design rationale and func- tions of the tool were presented. It was based on the 3D CAD software, SolidWorks, and embedded in it by means of DLL （dynamic link library）. It was a plug-in customized with the SolidWorks API and Visual Basic, and with knowledge of computer graphics. It can treat with satellite assembly in SolidWorks to carry on the following blinding analysis functions： setting attributes for sensor optical cone, painting blinding chart, and computing blinding ratio.
