- Abstract
Based on the mathematical model of magnitude transmission from 4-degrees of freedom (4-DoF) space to 6-DoF space and the target acoustic signal simulation technology, a 6-DoF underwater ultra-short baseline positioning and measurement device is designed and developed. The device consists of an anechoic pool, a 4-DoF measurement and control system for the pool, a 4-DoF expansion installation device, a target analog acoustic beacon, a hydrophone, a data controller, and standard instruments such as standard steel tape, universal angle ruler, sound velocity profiler. It has the ability of 6-DoF underwater positioning and measurement, and solves the problem of positioning and measurement in the small-scale pool for large positioning distance. Through the analysis and evaluation of measurement uncertainty, it is concluded that the relative synthetic standard uncertainty of the device is 0.34%. The experiment verifies the stability and the various functions of the device, and meets the metrological verification requirements of Ultra-Short Baseline Hydroacoustic locator (JJG (Transportation) 152-2020). At the same time, it plays an exemplary role in the construction of sonar system measurement experiment curriculum, experimental teaching, measurement certification in colleges and universities.
