摘要
以BLUE算法和GDOP为基本定位算法和精度分析工具,评估多基地雷达的定位性能,建立以GDOP最小值最小和有效监控区最大为目标的多基地雷达布站优化模型。仿真结果表明,通过以下措施可提高定位性能:①增加收发站总数;②采取扇形方式布站;③优先增加部署接收站;④交替部署收发站;⑤通过优化模型优化扇形布站分布角总和。
To estimate the location performance of multi-static radar, the best linear unbiased estimator （BLUE） is used as the basic location arithmetic and geometric dilution of precision （GDOP） as tool of precision analysis. Then sites distribution optimization model with objectives of minimizing minimum GDOP and maximizing the effective surveillance region is established. After simulating, the following actions can be taken to prove the location performance： ①increasing the total number of receiving and transmitting sites; ② fan shaped sites distribution;③ giving priority to increasing receiving sites; ④distributing receiving and transmitting sites in turn;⑤ optimizing the fan shaped sites distribution total angle.
