| 摘 要： | 针对双基地声纳系统存在冗余信息的问题,基于线性最小二乘估计理论提出了一种定位优化算法,建立了T/R？R型声纳系统水下定位的数学模型。通过MATLAB软件的仿真分析,给出了影响该算法性能的各个因素,并与传统TOL算法进行了对比。仿真结果表明,采用线性最小二乘估计算法能更好地利用系统测量的冗余信息,显著提高双基地声纳基线区和侧边区的定位精度。该算法具有受基线长度和站址误差影响小等优点,是一种具有工程应用价值的双基地声纳定位算法。本文的研究可为多基地声纳定位优化问题的研究提供理论基础。

| Abstract: | In the view of the redundant information problem of a bistatic sonar system,an optimal localization algorithm based on the linear least squares estimation is proposed.A mathematical model of underwater positioning is established based on a certain bistatic sonar.Through numerical simulation with the software MATLAB,the effect of the system parameters on localization accuracy is investigated.Also,the algorithm is compared with the time-only-localization(TOL) method.Simulation results show that the proposed a... |
