摘要
针对我国交会对接过程中出现目标靶标被遮挡的现象,研究手控对接过程中靶标被遮挡的可能性,并仿真了遮挡过程。首先分析了目标飞行器前锥面和飞船自身以及帆板在交会对接中形成遮挡的特点,基于空间三维矢量投射原理,建立了各部分对靶标底盘产生遮挡的投影模型和遮挡模型,基于交会对接运动规律以及太阳矢量,计算获取了遮挡方位以及遮挡时间,并通过三维图形实时渲染和轨迹变化曲线图再现了遮挡过程,直观易懂。经与神八、神九交会对接光照遮挡比对,验证了方法的正确性及有效性。该方法已成功应用于地面支持任务中。
The phenomenon of target obscuring during the rendezvous and docking（ RVD） of Shenzhou has occurred. The possibility of target obscuring during manual RVD was studied and the process of target obscuring was simulated in this study. Firstly,the characteristics of target obscuring formed during RVD by the front-conical-surface,the spaceship and the solar arrays were analyzed.Then the projection model and the obscuring model of each part related to the emerging of target obscuring were established. Based on the spatial three-dimensional vector transmission principle and the motional rules of the RVD,the obscuring directions and times were calculated and obtained. In addition,the process of target obscuring was duplicated by 3D real-time graphics rendering and the curve of trajectory transformation. The results were intuitive and easy to understand. The correctness and effectiveness of the method were verified by comparing the simulation results with the obscuring in Shenzhou 8 and Shenzhou 9 RVD tasks. The method has been successfully applied to the ground support missions.
