基于水下滑翔机的水听器阵设计与探测性能分析

Design and reconnaissance performance analysis of hydrophone array based on underwater glider

以水下滑翔机为平台,设计了一种被动水听器阵,并详细分析了该基于水下滑翔机的水听器阵的探测性能。理论与仿真分析表明,其对声源级230 dB@3 kHz主动声纳信号的有效作用距离最大可达100 km以上,对声源级170 dB@10 kHz水声通信信号的有效作用距离最大可达15 km以上,对声源级140 dB@100 Hz辐射噪声信号的有效作用距离最大可达9 km以上,系统探测性能良好。

Taking the underwater glider as the platform,a hydrophone array is designed and the reconnaissance performance of this hydrophone array based on the underwater glider is analyzed in detail.The theoretical and simulation analysis shows that the effective reconnaissance distance of the hydrophone array to the active sonar signal(230 dB@3 kHz)can reach more than 100 km,to the underwater acoustic communication signal(170 dB@10 kHz)can reach more than 15 km,and to the radiated noise signal(140 dB@100 Hz)can reach more than 9 km.Therefore the system has good reconnaissance performance.
