摘　　要：空间目标监视雷达是空间监视领域的骨干装备,与常规防空雷达相比,需要增加空间目标轨道确定核心功能,而轨道改进是实现该功能的重要组成模块,轨道改进模块的研制涉及非常复杂的航天动力学知识,这对从事雷达系统设计的非轨道力学专业的研究人员来说带来极大困难。为此,本文以空间目标雷达定轨中的批处理轨道改进计算为例,介绍了它的数学原理,给出了程序设计思路和函数接口实现,并与ODTK软件进行了仿真对比。实验结果验证了软件设计的有效性,表明本文设计的函数接口可以辅助科研人员进行雷达系统设计。Space target surveillance radar is the backbone equipment in the field of space surveillance.Compared with conventional air defense radars,the core function of space target orbit determination must be added to the radar system,and orbit improvement is an important component to realize this function.The development of this module requires very complex aerospace dynamics knowledge,which brings great difficulties to non-orbit mechanics researchers engaged in radar system design.For this reason,taking the batch processing orbit improvement calculation in the space target radar orbit determination as an example,this paper introduces its mathematical principles,gives the program design ideas and the realization of the function interface,and makes a simulation comparison with ODTK software.The experimental results verify the effectiveness of the software design in this paper,and show that the designed function interface can assist researchers in radar system design.
