空间物理过程时空协同探测的覆盖分析方法研究

针对空间物理过程时空协同探测任务的定量化探测覆盖分析需求, 在采用时空相关函数方法描述和分析空间物理时空过程的基础上, 提出一种基于θ-t_R覆盖图的探测覆盖分析方法. 通过分析不同设计方案在一定累计时间周期内的θ-t_R覆盖图, 根据其覆盖范围的不同选择所需要的设计方案. 采用该方法对两条共轨道面椭圆轨道的时空协同探测过程进行了定量的覆盖分析, 验证了该方法的有效性. 

A Method of Coverage Analysis for Multipoint Coupling Plasma Detection on Space Processes

So far the analysis method of detective coverage in multipoint coupling plasma detective missions on space processes is still at the stage of qualitative analysis. Statistical analysis of a certain space region for the satellites also cannot undergo further quantitative analysis. To meet the needs of fast development of space science missions, on the basis of correlation function and space processes analysis, a coverage analysis method based on θ-t_R coverage diagram is proposed. By analysis of θ-t_R coverage diagram in accumulative time period of various design alternative, the appropriate design can be chosen according to the characteristics of coverage range. Then quantitative analysis is made on multipoint coupling detective processes of two coplanar elliptic orbits, with which the method is verified.
