摘要:

对繁杂机场场面监视点进行优化定位,能够有效提高机场场面的运行效率,如何对监视点进行实时高精度定位一直是多点定位系统不断研究的技术难题。针对多点定位非线性方程解算问题,提出了自适应小生境弹射粒子群算法结合 Taylor 级数展开法的优化算法,将自适应小生境弹射粒子群算法搜索的定位结果作为 Taylor 级数迭代的初始参考点,解决了传统 Taylor 级数展开法依赖初始参考点选取的问题。结果表明:改进的粒子群算法结合 Taylor 级数展开法的定位估计精度相较于单纯的 Taylor 级数展开法有较大提升。

Abstract: Optimizing the monitoring points of complicated airport scenes can effectively improve the operating efficiency of airport scenes. However, the real-time positioning of monitoring points with high precision is still unresolved. Aiming at this problem, an adaptive niche ejection particle swarm algorithm combined with Taylor series expansion method is proposed. The positioning results of the proposed algorithm are taken as initial reference points for Taylor series iteration, solving the dependence of traditional Taylor series expansion method on the initial reference point selection. Simulation results show that the positioning estimation accuracy of the improved particle swarm algorithm combined with the Taylor series expansion method is greatly improved compared with the simple Taylor series expansion method.

Key words:  , airport scene surveillance, multipoint positioning, self-adaptive particle swarm algorithm, niche ejection strategy
