摘要:
针对水下2个相干目标的远程探测问题,本文提出了一种基于前后向空间平均的声矢量圆阵方位估计方法。该方法根据中心对称声矢量圆阵的结构特性,将声矢量传感器顺序重新排列建立中心对称的阵列形式。利用声压振速联合处理构建声压与振速的互协方差矩阵,引入后向互协方差矩阵,从而通过平均前向和后向矩阵得到前后向平均的互协方差矩阵。采用最小方差无畸变响应波束形成器完成2个相干目标的方位估计。理论分析与仿真结果表明:与声压处理方法、声压振速独立处理方法以及相位模态域声压振速联合处理方法相比,本文所提方法具有较高的角分辨能力、方位估计精度以及较强的噪声抑制能力;相比相位模态域声压振速联合处理方法,该方法可适用的频带范围更宽。试验结果进一步验证了该方法具有较好的相干双目标方位估计能力。
