基于GDOP分析模型的双星无源定位系统精度研究

Analysis of Location Precision in Dual-satellite Passive Location System Based on GDOP

  • 摘要: 双星无源定位系统因其良好的隐蔽性能和高效的定位特征,被广泛地应用在现代化电子对战中。定位精度是决定该系统定位可靠性的重要指标,因此如何确定系统定位精度是双星无源定位系统研究的关键。本研究以双星无源定位TDOA/FDOA联合估计模型为基础,利用几何稀疏误差(GDOP)分析方法,建立双星无源定位系统精度分析模型,对比分析了不同因素对双星无源定位系统精度的影响,研究系统定位精度特性,得出了定位精度曲线。

     

    Abstract: The dual-satellite passive location system, for its good concealment performance and efficient positioning characteristics, is widely used in modern electronic warfare. Positioning accuracy is an important index to determine the reliability of the system positioning, so how to determine the system positioning accuracy is the key to binary passive positioning system research. Based on the TDOA/FDOA joint estimation model of binary star passive location, the Geometric Dilution Precision(GDOP)analysis method was used to establish the error analysis system of the Dual-satellite Passive Location system. Combined with examples, the influences of different factors on the accuracy of binary passive positioning system were compared. Moreover, the positioning accuracy characteristics of the dual-satellite passive location system were also investigated,and positioning accuracy curve is obtained.
