| 摘 要： | 提出了一种基于最小最大决策的三站时差定位布阵优化方法,以提高系统对目标区域的整体定位精度。应用基于最小最大决策的最优化理论,建立布阵优化问题的数学模型。该模型以三站坐标为决策变量,以目标区域的最大水平定位误差最小为目标函数,然后运用基于最小最大决策的最优化算法,求解模型的最优解,并将此最优解作为三站时差定位系统的最优布阵。仿真结果与理论计算一致,验证了这种布阵优化结果的最优性。

| Abstract: | An optimization method of station layout based on minimax principle for tri-station time difference of arrival(TDOA) location system is presented.The optimization theory based on minimax principle is used to build a mathematical model for layout optimization.In this model,the coordinates of the three stations are regarded as decision variable,minimization of the maximum horizontal dilution of precision(HDOP) is regarded as objective function.Then the optimal solution is studied by using optimization algorit... |
