This paper introduces an approach to localize and track an unknown number of non-cooperative surface vessels based on passive acoustic sensing of their noise radiated underwater. Time-Difference of Arrival (TDOA) measurements are extracted from pairs of hydrophones, and a recently introduced Bayesian framework for multi-object tracking is employed to detect and track vessels from TDOA measurements. Results based on data from a three-dimensional compact hydrophone array towed by an autonomous vehicle confirm that non-cooperative surface vessels can be detected and tracked.
本文介绍了一种基于被动声学传感水下辐射噪声来定位和跟踪未知数量非合作水面舰艇的方法。从水听器对中提取到达时间差（TDOA）测量值，并采用最近引入的用于多目标跟踪的贝叶斯框架，根据TDOA测量值来检测和跟踪舰艇。基于由自主航行器拖曳的三维紧凑型水听器阵列数据的结果证实，可以检测和跟踪非合作水面舰艇。
