摘　　要：讨论了组网条件下影响制导雷达数据融合精度的主要因素,分析了若干主要误差源,采用椭球面、线偏差等高精度计算方法,推导出多测量站支援受援站的计算公式及误差协方差阵,并进行了系统仿真,仿真结果表明了该方法的有效性。On the condition of radar net, the main factors that effect the precision of guidance radar data fusion is discussed in detail, and several main error sources are analyzed. When one radar station can be supported by a few other radar stations in the guidance radar net, by adopting some high precision approaches such as ellipse globe and linear bias, the data fusion process formula and error matrix of this radar station are derived. The Monte Carlo simulation approach is used to analyze the precision of data fusion in guidance radar net, and the result analysis of simulation is also given.
