单站多普勒跟踪定轨的优化算法

由于低轨道小卫星应用的日益广泛，在轨卫星数目的迅速膨胀，对传统的多个地面站相互协调管理卫星领域模式提出了挑战。小卫星的低成本特性必然要求存在与之相应的地面站设施降低复杂性、降低成本。本文针对当前已提出的单站多普勒定轨方案，进一步研究了多普勒定轨的有关方法，提出和建立了多普勒定轨的优化算法与模型，最后进行了仿真分析与模型的有效性验证。

Optimal Algorithm of Orbit Tracking and Determination by Single Station Dopper Radar

With the wide application of the LEO small satellite,the number of orbited satellites is rapidly expanding,which means a challenge for the traditional management of the satellites using multiple ground stations.And the characteristic of low cost of small satellite requires the low complexity and low cost of the infrastructure of ground station in essential.Referring to the current orbit determination scheme using Doppler radar by single ground station,this paper studies the principle of orbit determination,and builds up the novel optimal algorithm of orbit determination.In the last,the simulation result and the model validation are analyzed.
