| 摘要 |
舷侧阵声纳是舰船特别是水下无人潜航器和潜艇使用的重要探测装备，由于其阵元安装在艇壳表面，工作环境极其恶劣，艇壳振动、流噪声等干扰会导致所获取各阵元数据的信噪比不一致，从而严重影响声纳探测性能。本文给出了阵元信噪比不一致性对阵输出信噪比影响的理论推导，并分析了其对不同波束形成算法的影响。研究表明，普通波束形成算法对阵元信噪比不一致的宽容性较差，而采用子阵分割方案的CTA算法对此有较强的宽容性。 |

Flank Array Sonar(FAS)is a important sonar equipment for submarines and UUVs．Becausse its installation place(in the two flanks of vehicles)，the vibration of hull and near-field generated flow noise bring on inconsistent SNR on sensors of the array．The inconsistent SNR on sensops will lcads to the degradation of the detection performance of FAS．111is paper discussed this problem and the theoretical analysis of the
inconsistent SNR on sensors was deduced in details．The results of time—delay．sum algorithm and CTA algorithm based on sub array method to inconsistent SNR on sensors were compared，and the result shows that the more robust of sub array method has． |
