摘　　要：目前国内缺少针对雷达观测数据的空间目标定轨开源软件,给从事雷达系统设计的非轨道力学专业的研究人员带来不便。研制定轨软件的核心内容是摄动加速度计算,它是实现高精度数值轨道计算的基础。为此,本文以地球引力为例,介绍了地球非球形引力摄动的数学原理,给出了加速度计算的程序设计思路,实现了接口函数并集成到笔者前期开发的雷达定轨函数库(RadarOrbDet)中。实验结果验证了本文接口函数的有效性,表明该定轨函数库可以辅助科研人员进行雷达系统设计。At present,there is a lack of open source software for space target orbit determination based on radar observation data in China,which brings inconvenience to non-orbital mechanics researchers engaged in radar system design.The core content of the development of orbit determination software is the calculation of perturbation acceleration,which is the basis for realizing high-precision numerical orbit calculation.To this end,this article takes the gravity of the earth as an example,introduces the mathematical principles of the non-spherical gravitational perturbation of the earth,gives the program design ideas for acceleration calculation,realizes the interface function and integrates it into the radar orbit determination library(RadarOrbDet)in.The experimental results verify the effectiveness of the interface function in this paper,and show that the orbit determination function library can assist scientific researchers in radar system design.
