摘　　要：纳机电矢量水听器是一种新型的声音传感器,根据鱼类侧线听觉仿生学原理设计。文中对这种传感器的定向功能进行了研究,综合国内外各种文献中的几种单矢量水听器定向算法,选取了波束形成法应用于纳机电矢量水听器。并对水听器的测向功能进行了室外水库测试,实验结果表明:在室外水库较复杂的环境中,纳机电矢量水听器能够实现声目标定位,为下一步的海洋真实环境测试打下基础。According to the auditory principle of fish＇s stereocilium, a NEMS vector hydrophone is designed. The application of NEMS vector hydrophone to estimate the direction of arrive （DOA） signal was studied. According to various literature at home and abroad, many algorithm can be applied to vector hydrophone. The beam-forming approach is selected. Lake tests are performed to validate the theoretical results. Both the theoretical analysis and the results of tests proved that NEMS vector hydrophone can orient the sound target under the lake, laying a foundation for the marine test next step.
