摘　　要：光纤水听器(FOH)作为一种新型水声传感器,可应用于水下目标探测、石油天然气勘探、地震检测等军事和民用领域。随着海洋背景噪声的增大和水下目标降噪水平的提高,人们对FOH的性能要求也越来越高。因此,从FOH的主要发展方向、关键技术、新型FOH三个层面介绍了FOH技术,包括大规模FOH阵列、甚低频探测、深海远程传输、拖曳细线阵、窄线宽激光器、信号处理、光纤矢量水听器和分布式FOH等方面,对于FOH系统的理论研究和实际应用具有一定的指导意义。Fiber optic hydrophone(FOH) is a new type of underwater acoustic sensor, which can be used in both military and civilian fields such as underwater target detection, oil and natural gas prospecting, and earthquake inspection. With the increase of ocean ambient noise and the development of noise suppression techniques for the underwater targets, people’s demand for high-performance FOH is becoming more and more urgent. Therefore,this article introduces FOH technology from three aspects, including main development trends, key technologies and new-type FOH. In detail, large-scale FOH array, very low frequency detection, deep-sea and long-haul transmission, towed linear array, narrow-linewidth laser, signal processing, fiber optic vector hydrophone and distributed FOH are introduced. This research has certain guiding significance for the theoretical research and practical application of FOH system.
