中文摘要：

矢量传感器由声压传感器和振速传感器同心复合而成，由它构成的垂直矢量阵的空间增益相比于传统的声压阵能提高4．8dB。利用典型浅海环境中的仿真数据比较了垂直矢量阵的实际空间增益和理想空间增益，并分析了声源位置、阵元个数、矢量阵深度和信号频率对垂直矢量阵组合空间增益的影响，仿真分析结论对垂直矢量阵的应用具有参考价值。

英文摘要：

Vector sensor has concentric compound form of the acoustic pressure sensor and particle velocity sensor, which makes the spatial gain of vertical vector array improve 4. 8 dB. Having compared the spatial gain on vertical vector array and ideal gain by using a typical shallow water environment simulation data, the effect of the source depth, the number of elements, the depth of array and the signal frequency to the spatial gain are analyzed. This work has important value of referenee for the application of the vertical vector array.
