Abstract

Abstract: Ultra-short baseline (USBL) system is a commonly used underwater acoustic positioning system,but its positioning accuracy is limited by its small diameter and the design of array formation.A method to improve the positioning accuracy of USBL system is presented.The USBL system only measures the propagation time of acoustic signal once,locates the target through the basic arrays,and then acts data fusion on the valuable positioning results to obtain the final result.The simulation results show that the proposed method can effectively improve the reliability and positioning accuracy of the USBL system under low SNR.

Key words: data fusion, ultra-short baseline positioning system, 5-element planar array
