摘　　要：针对水下滑翔机缓动平台应用声矢量传感器用于水中移动目标探测时,传感器姿态不能准确测量导致目标方位输出精度低的问题,文中设计了一种具有姿态感知能力的声矢量传感器。首先,将姿态传感器集成应用于声矢量传感器设计,并对其进行参数测试;其次,将声矢量传感器集成在水下滑翔机平台,并在消声水池对声矢量传感器进行等效噪声声源级测量;最后,利用水下滑翔机平台搭载声矢量传感器开展目标探测试验,试验时以科考试验船为配合目标,检验声矢量传感器在水下滑翔机平台应用时对噪声源的目标方位估计能力。海试结果表明,经姿态校正后,目标方位估计结果与全球定位系统推算方位结果基本吻合,满足测向精度要求。文中研究可为声矢量传感器在水下滑翔机平台上的工程应用提供参考。In view of the fact that as current underwater glider slow-moving platform applies acoustic vector sensor to moving target detection in water,the sensor posture cannot be accurately measured to result in low-precision output of target azimuth,this study designed an acoustic vector sensor with attitude awareness capacity.First,the attitude sensor was integrated into the design of acoustic vector sensor,and parameter testing was performed;Second,the acoustic vector sensor was integrated into the underwater glider platform,and its equivalent noise source level was measured in an anechoic pool;Finally,target detection test was carried out with the acoustic vector sensor mounted on the underwater glider platform,in which a scientific research and test ship was taken as the target to evaluate the noise source azimuth estimation ability of the acoustic vector sensor which was applied to the underwater glider platform.Sea trial shows that,after the attitude correction,the estimation result of the target azimuth is basically consistent with that of the global positioning system,and meets the accuracy requirement of the direction finding.This research may provide reference for the engineering application of acoustic vector sensor to underwater glider platform.
