N2 - The ultra-short baseline (USBL) is an underwater localization method. It widely applied in the underwater localization system. However, as there are environmental interference and measurement error, the localization accuracy is poor, which can not meet the requirements. To order to enhance the localization accuracy, in this paper, an underwater accurate localization method exploring phase difference and Kalman filter is presented. In this method, we utilize a non-equidistant quaternary original array to receive acoustic signals from an underwater target. Then we explore the Kalman filtering algorithm to process the accurate acoustic signals and gain the phase difference. In the end, we get the localization result of the underwater target. Experimental results indicated the underwater localization method can improve the underwater localization performance.
