摘要
研究了无源双站测向交叉定位原理,推导出双站测向交叉定位的精度公式。并给出了定位精度几何分布图(GDOP)与相对误差曲线图,详细分析了双站测向定位中参数对精度的影响。仿真结果和性能分析为该类系统的技术作战运用提供了理论支持。
Relevant precision expressions by expounding theory of Bi-static DOA passive location is deducted in this paper.According to the theory,Geometric Dilution of Precision（GDOP） and relative error curve were given,then each positional parameters which affect the locating accuracy is analyzed.Finally,the simulation results and performance analysis provide operational technical principle for such a system in battle.
