摘　　要：应用三元组的阵元结构和最佳阵处理算法可以解决宽带下左右舷分辨这一现代拖线阵声纳设计的难题。文章首先简介了一种获得三元组拖线阵声纳宽带最佳阵处理垂直指向性图的方法,并阐述了如何基于垂直指向性图进行左右舷分辨。然后在大量仿真基础上,深入探讨了噪声结构、目标方位、阵横滚等诸要素对左右舷判别性能的影响,最后作了规律总结。Adopting the line array of triplets and applying the optimal array processing can realize the port/starboard discrimination, which is one of the most difficult problem in the design of modem towed line sonar. A method to obtain the vertical directivity of hydrophone triplets towed line sonar by the optimal array processing is introduced in brief at first. And the way how to use the vertical directivity to discriminate the port/starboard is explained. Based on large quantities of simulation experiments, the influence, of such factors as the structure of noise, the direction of object and the roll of array, on the discriminating performance is researched, Some rules are summarized at last.
