航天器及部位投影形状不确定性的建模与仿真

Uncertainty Modeling and Simulating of Spacecraft and Its Parts Projection Shapes

在未来空间作战中,航天器将成为重要的作战装备,同时也将是敌对双方重点打击的对象。通过投影形状确定航天器类型或者航天器毁伤部位的毁伤度,可以为及时采取相应的措施提供决策依据。结合航天器的三维空间实体描述,给出了航天器投影多边形的误差带模型以及航天器毁伤部位投影多边形的面积误差模型。通过实例仿真分析得出,通过构建航天器及其毁伤部位多方位投影形状数据库,建立多边形面元不确定性模型,结合先进的计算机技术和人工智能技术,确定航天器类型及其可能毁伤部位的毁伤度是可行的。

Spacecraft will be an important equipment and striking object in future space operation. Confirming types of spacecraft or degree of destructed parts by the shapes of projection, decision gist could be provided to adopt relevant measurements. Combining with three-dimensional spatial entity description, projection polygonal error band mode of spacecraft and error area mode of spacecraft destructed parts are given. By simulation analyzing, it concludes that it＇s feasible to confirm types of spacecraft and degree of destructed parts, if projection polygonal database of spacecraft and destructed parts, modeling polygonal area uncertainty model are constructed by advanced computer and artificial intelligence technologies.
