摘要
针对我国海上维权不能及时发现非法海洋调查船、海洋资源勘探船作业的问题,设计了基于水声技术的非法作业船只远程监听系统。系统基于低频带宽接收水听器基阵,具有对脉冲信号的远程侦测、识别功能。可扩展处理平台ZYNQ控制多路信号同步采样,对采集的数据进行最小方差无畸变响应(MVDR)测向、矢量测向。嵌入式处理器将监测结果通过水声通信模块传送到数据中心,从而获取非法侵权船只的实时作业活动。
Aiming at problems that illegal operation of ocean survey ships and marine resources exploration ships cannot be found by maritime rights protection in China,design a remote monitoring system of illegal operation ships based on underwater acoustic technology. The system is based on low frequency band-width receiving hydrophone arrays and has function of remote detection and identification on pulse signal. Extendible processing platform,ZYNQ controls synchronous sampling of multi-channel signal and process collected datas with MVDR estimation and vector estimation. The embedded processor transmits the monitoring result to data center by the underwater acoustic communication module,thus the data center can obtain real-time activities of illegal infringement ships.
