| 摘 要： | 针对目前高精度测速系统布站情况,提出了一种基于测站数据组合的目标参数计算方法,以几何因子(GDOP)为度量标准,建立了布站情况分析的数学模型。通过目标至主站和各副站的夹角情况,构造最小、最大评价函数,同时根据基线情况,建立评价原则,分析其布站对目标参数精度的影响。研究结果可为实时数据的可靠性分析及外测事后数据处理精度分析提供技术支持。

| Abstract: | According to the geometrical distribution of the high accuracy velocity measuring(HAVM)system,the object parameter algorithm based on measurement station data combination is presented.By the GDOP,the model of station distribution analysis is set up.According to the angles of the object to main station and to slave stations,the minimum and maximum evaluation functions are constructed,and the evaluation principle is put forward based on base line.Using the methods,described the above effect on trajectory parameter precision impacted by station distribution is analyzed separately.The results obtained in this paper can be used to analyze the reliability of real-time data,and evaluate the precision of data processing of exterior ballistic measurement. |
