| 中文摘要: |
| 针对多基地、多浮标定位系统，不同的布站方式、布站数量对系统定位误差均有一定影响。从定位误差方程推导出定位误差最优目标函数，探讨了在有限的条件下如何提高系统定位精度，给出了精度与布站数、布站距离、布站位置之间的关系。通过分析基本布站方式，以及布站方式与精度之间的关系，根据得到的分析方法，对三种布站方式进行了精度分析，得到了与实际情况相符的结果。通过Matlab仿真，给出了3~8个浮标与定位精度的效果图示，分析了布站数与定位范围、布站半径与布站面积之间的关系，并得到最佳布站方式及布站半径，在实际应用中具有较好的参考价值和指导意义。 |
| 英文摘要: |
| In multi-station and multi-buoy positioning systems, the system positioning error is influenced by different station arrangement methods and the number of buoy stations. The optimal objective function of the positioning system was deduced from the error function. The improvement method for sonar positioning accuracy in limited conditions was proposed. By analyzing the basic station arrangement and the relationship between precision and station ar-rangement, three kinds of station arrangement methods were compared according to the proposed method. Experi-mental results showed consistent performance as the actual situation. The relationships between the precision and the number of buoy stations, the radius of buoy station and station location were discussed from simulation, indicating that the proposed method could achieve the best arrangement of buoy stations and the best radius of the stations. |
