中文摘要:
      利用矢量线阵可以提高对目标参数估计的性能,探讨了矢量线阵MUSIC算法的抗左右舷模糊性能和抗空间混叠性能。理论研究和外场试验结果表明,矢量线阵消除了声压线阵MUSIC方位谱的左右舷模糊,在阵元个数保持不变的条件下,空间降采样时,矢量线阵MUSIC空间谱不仅提高了方位估计的精度,而且能够抗空间混叠,在相同的条件下,矢量线阵MUSIC空间谱的抗空间混叠性能明显优于矢量阵常规波束形成方法。
英文摘要:
      The performance of parameter estimation of underwater targets can be improved by using vector-hydrophone array.The ability of removing the DOA estimation ambiguity and suppressing grating lobes are analyzed based on vector hydrophone linear array.The theoretical results and experimental results show that the DOA estimation ambiguity lying in the pressure hydrophone linear array can be removed by using vector-hydrophone linear array.The resolution of DOA estimation can be improved when the wavefield is de-sampled with MUSIC algorithm,and the grating lobes can be suppressed.The ability of suppressing grating lobes of MUSIC algorithm is better than that of conventional beamforming based on vector-hydrophone linear array.
