摘要
为实现前沿阵地和地面防空两种典型应用约束条件下到达时间差(Time Difference of Arrival,TDOA)定位的自动布站优化,分析了这两种典型约束条件下的基站长度、站点间角度等对定位精度的影响.提出了基于自适应差分进化(Differential Evolution,DE)算法的TDOA自动布站优化策略.采用该算法对这两种约束条件下的自动布站优化进行了仿真分析,并对自适应DE算法计算复杂度进行了分析.结果表明,自适应DE算法的自动布站复杂度低,收敛快速,与定位误差分析一致,具有较好的全局寻优能力.
Abstract
To achieve automatic station distribution optimization for time difference of arrival(TDOA)under the two typical application constraints of forward positions and ground air de-fense,the impact of baseline length,distances between stations,and other factors on location pre-cision are analyzed under the two typical application constraints.TDOA automatic station distri-bution optimization strategy based on adaptive differential evolution(DE)algorithm is proposed.The algorithm is used to simulate and analyze the automatic station distribution optimization un-der these two constraints,and the computational complexity of the adaptive DE algorithm is ana-lyzed.The results show that the adaptive DE algorithm has lower computational complexity,faster convergence,consistency with positioning error analysis,and better global optimization ability for automatic station distribution.
