| 摘 要： | 文章从分析定位标定系统海试数据处理结果入手,提出利用拟合检定方法评估水声测量定位精度。仿真测试和海试数据验证结果表明,利用拟合检定方法评估的水声定位精度比实际标定精度偏小,基本可以反映实际测量数据的标定精度,作出置信分析的拟合评估精度值更接近实际标定精度值。此方法可以作为定位标定的补充,给出测量精度指标的估计值。

| Abstract: | In this paper,a method is proposed based on fitting test to evaluate water acoustic measurement positioning precision,which was based on analysis processing results of sea trial data of positioning calibration system.Simulation testing and testing results of sea trial data show that acoustic positioning precision gained by the method is smaller than the actual measurement data of the calibration precision,and it can reflect the actual measurement data of the calibration precision,and the value of the fitting assessment accuracy of confidence analysis is closer to that of actual calibration precision.The method can be used as supplement of positioning calibration,by which the assessment value of measurement precision index is gained. |
