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.
