| 摘 要： | 首先建立了位于反射界面附近的三维圆柱形矢量传感器阵列的数学模型；基于此阵列的“矢量-空间”域，提出了一种新的相干信号预处理算法，并分析了算法的性能。数值仿真验证了在不同的阵列参数下算法的有效性。理论推导和数值仿真表明此算法具有减少整个阵列空间孔径的损失，增加平滑相干信号的数目等优点。

| Abstract: | The measurement model is first set for the 3-D cylindrical array with multi-vector-hydrophones, which is located on or near a reflecting boundary. A new coherent signals preprocessing algorithm is proposed based on the “vector-spatial” field of the array. And the performance of the proposed algorithm is examined. In case of different array’s parameters, the effectiveness of the proposed algorithm is tested via the simulations. The advantages of the proposed algorithm include reducing losses in the overall array’s spatial aperture and increasing the maximum number of smoothed coherent sources. |
