多点定位系统的布站方法研究

Study on Station Layout Method of MLAT System

针对多点定位系统基站布局直接影响目标定位精度的问题,提出一种基于粒子群优化算法的基站优化布局方法。该方法以几何分布因子GDOP为适应度函数,实现场面基站的最优布站。Matlab仿真结果表明,该方法能够优化基站布局,提高目标定位精度。

Aiming at the problem that the station position of the multilateration(MLAT)system directly affects the target positioning accuracy,a scheme of the optical layout which was based on particle swarm optimization algorithm was proposed.The method used the geometric distribution GDOP as the fitness function,to make optimal layout of the ground stations.Matlab simulation results showed that the proposed method could optimize the base station layout and improve the accuracy of target location.
