【摘要】 伴随着人类对海洋的探索,声纳接收阵被广泛应用于海洋环境监测、水下目标探测和水声通信等领域,衡量声纳接收阵列性能最重要的指标之一是自噪声,水听器自噪声要低于需要测量的海洋环境噪声一定量级,才能对海洋环境噪声和其他声信号进行准确测量,除了水听器自噪声,水听器在成阵过程中也会不可避免的引入各种噪声,水听器阵列噪声抑制技术是一项系统工程。本文研究了水听器阵列主要噪声来源和噪声指标,以及多水听器成阵关键技术。更多还原

【Abstract】 With the exploration of the ocean by humans, sonar receiving arrays have been widely applied in the fields of ocean environment monitoring, underwater target detection, and acoustic communication. One of the most important indicators for measuring the performance of sonar receiving arrays is self-noise. The self-noise of hydrophones should be lower than a certain level of the ocean environment noise that needs to be measured in order to accurately measure the ocean environment noise and other acoustic signals. In addition to self-noise, various noises are inevitably introduced during the process of hydrophone array formation. Hydrophone array noise suppression technology is a systematic engineering. This article studies the main sources and indicators of hydrophone array noise, as well as the key technologies of multi-hydrophone array formation.更多还原
