| Abstract: | 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. |

| Keywords: | virtual instrument underwater acoustic signal uniform circular array direction of arrival estimation |
