Abstract

Passive localization of a sound source in the deep ocean is investigated in this study. The source can be localized by taking advantage of a cross-correlation function matching technique. When a two-sensor vertical array is used in the deep ocean, two types of side lobe curves appear in the ambiguity surface of the localization. The side lobe curves are analytically expressed and they are then used as indicators of the localization result instead of the scanning point with the maximum power. Simulation and experiment demonstrate the performance of the proposed passive localization method.

摘要

本研究对深海中声源的被动定位进行了探讨。利用互相关函数匹配技术可对声源进行定位。当在深海中使用双传感器垂直阵列时，定位模糊面中会出现两种旁瓣曲线。对旁瓣曲线进行了解析式表达，随后将其用作定位结果的指标，而非最大功率扫描点。仿真和实验验证了所提被动定位方法的性能。
