摘要 利用LabVIEW软件,通过8通道数据采集卡和均匀圆阵对水下目标的噪声进行采集和处理。结合一维直线阵波束形成理论,实现了对水下目标二维方向角估计实验研究和算法验证。实验证明利用虚拟仪器方便地实现了对水声信号的采集、处理,以及在方位估计时,为传感器布阵和算法的确定提供参考。 The noise of the underwater target is acquired and processed by using LabVIEW and 8-channels data acquisition. Based on line array beamforming theory, the estimation of the underwater target 2D angle and corresponding algorithm is studied by use of the uniform circular array. The experiment results show that it is convenient to use the virtual instrument for data acquisition and analysis of the underwater acoustic signal, and help us to determine the structure and the algorithm for direction of arrival （DOA） estimation.
