| 摘 要： | 建立了水平L-型矢量水听器阵列的数据模型，研究了利用ESPRIT算法同时对目标的水平方位角和仰角进行高分辨率角度估计，仿真L-型矢量水听器阵对单个源和多个源的方位估计情况，并和相同阵型的声压阵方位估计性能进行比较，结果表明，相对于声压阵，矢量阵可以在不增加阵孔径的前提下提高对单源方位估计的精度，获得的增益为6dB左右，同时提高了对多目标方位的分辨能力。

| Abstract: | A data model of an L-shaped vector-sensor array was built in order to improve the ability to distingnish a multisource. The azimuth angle and elevation angle were estimated using the ESPRIT algorithm based on an L-shaped vector-sensor array as well as an L-shaped pressure sensor array. Simulation of direction of arrival(DOA) estimation for a single source and two sources was carried out. The results indicate that higher resolution of DOA estimation can be obtained using the ESPRIT algorithm based on vector-sensor array than that based on a pressure sensor array at the same aperture. The gain was about 6?dB. The distinguishing capability was related to the difference of direction cosine between two sources. |
