摘要

摘要: 文中结合某水下平台舷侧的实际需求, 基于分布反馈式(DFB)光纤激光水听器技术, 设计小尺度舷侧模块。仿真中采用分层介质中的弹性波模型建立声障板模型, 并对声障板合理选材, 制备了4阵元DFB光纤激光水听器舷侧模块, 并测试了舷侧模块的灵敏度。实验结果表明, 舷侧模块中水听器相对灵敏度提高, 响应相对平坦, 初步验证了设计方案的可行性。

Abstract: A small-scale side module was designed based on distributed-feedback(DFB) fiber laser hydrophone technology. An acoustical baffle model was designed using an elastic wave model in a layer media. After a reasonable selection of materials for the acoustic baffle, a four-array DFB fiber laser hydrophone side module was fabricated. The sensitivities and directivities of the side modules were tested. The experimental results demonstrated that the relative sensitivity of the hydrophone module was enhanced and the response was flat. The feasibility of the scheme was preliminarily verified.
