摘要
给出了基于声波到达方位(BOL)的双基地声呐定位算法,分别研究了基线长度和角度测量误差等因素对该算法定位精度的影响。通过数值仿真,给出了不同条件下误差的几何分布。仿真结果表明,双基地BOL算法的定位精度与基线长度有关,随着基线长度的增加,定位精度提高;角度测量误差对BOL算法的定位精度影响较大。
In this paper,the Bear Only Localization(BOL)algorithm for bistatic sonar is presented.The localization accuracy of the algorithm for different baseline length and bear measurement error is studied.Through numerical simulation,the Geometrical Dilution of Precision(GDOP)is given.The sim-ulating re sults show that the localization accuracy of BOL algorithm is improved when the length of baseline is long.The bear measurement error has more effect on localization accuracy of BOL algo-rithm.[
