水声定位标定系统水下基准位置不确定度分析

摘要

In acoustic positioning system, the measuring accuracy of the underwater benchmark position (the simulation of object acoustic signal) directly affect evaluation of the position error of acoustic positioning system. Through analysising uncertainty of the underwater benchmark position, provide theoretical reference for the system to reduce measurement error of acoustic positioning system. The sea test results proved that the uncertainty analysis method is effective to improve acoustic positioning system calibration precision.%水声定位标定系统中水下基准(模拟目标声信号)位置的测量精度直接影响到对水声定位系统定位误差的考核.通过对水下基准中心位置不确定度的分析,为系统减小水声定位系统测量误差提供了理论参考,经海试证明该不确定度分析方法对提高水声定位系统标定精度有效.
