| 摘 要： | 将匹配场原理应用到单矢量水听器上,实现对目标声源的被动定位。对常用的2种Bartlett处理器进行仿真分析,提出了一种改进的Bartlett处理器,可以抑制旁瓣个数并提高主瓣强度。通过试验数据分析,在1.3 km的范围内,接收信噪比不低于10 dB时,测距和测向误差可以控制在10%以内。该研究为单矢量水听器的实际应用提供了重要的参考依据。

| Abstract: | Matched field principle is applied to single vector hydrophone to realize passive location of target acoustic source.Two kinds of commonly used Bartlett processor are simulated.An improved Bartlett processor which can both restrain the side lobe numbers and improve the main lobe intensity is proposed.Through analyzing experimental data,at the range of 1.3 km,when the SNR is not less than 10 dB,error of ranging and direction finding can be controlled within 10 ％.The study provides important reference for practical application of single vector hydrophone. |
