| 摘 要： | 本文提出用阵元间互相关作为基元加权求和形成波束(相关阵)，并给出用来抑制线阵局部强相关干扰的一种权向量实现方法。海上试验数据处理结果表明，利用本文提出的权向量实现相关阵比CBF阵有较高的信噪比增益和较好的抗噪声干扰能力。

| Abstract: | In this paper the beam is formed based on the sum of weighed cross-correlations (correlation arrays), where a set of weighing coefficient is given in order to restrain the effect of local correlative noise on the line array sonar. It is shown experimentally that the gain of correlation array using the set of weighing coefficient is higher and the anti-perturbation performance is better than those of the CBF arrays. |
