摘　　要：针对声呐基阵实船安装后阵元接收性能受艏端内声散射干扰及导流罩透声性能差异影响,实际接收性能难以准确校准的问题,提出基于标准水声源比较法的圆柱形基阵阵元灵敏度原位校准方法。首先对校准原理及所涉及的圆弧距离修正法和循环叠加平均法进行分析,并以某圆柱形声呐基阵为对象,设计并开展了湖上验证试验,对试验数据进行计算分析,结果表明基于标准水声源比较法能够准确获取基阵阵元接收灵敏度性能及阵元间灵敏度一致性,研究工作可为声呐装备实船交付后的性能校准提供一种思路,完善对声呐装备的计量保障能力。Aiming at the problem that after the sonar array is installed on a real ship,the array element receiving per-formance is affected by the internal sound scattering interference at the bow end and the difference in sound transmission performance of the dome,and the actual receiving performance is difficult to calibrate accurately,an in-situ calibration meth-od of cylindrical sonar array elements sensitivity based on the standard water sound source comparison method is proposed.Firstly,the calibration principle and the involved arc distance correction method and cyclic superposition average method were described and analyzed.A cylindrical sonar was used as the object to design and carry out a verification test on the lake.The test data were calculated and analyzed,the results show that the standard water sound source comparison method can ac-curately obtain the receiving sensitivity performance of sonar array elements and the sensitivity consistency between the ar-ray elements.The research work can provide an idea for performance calibration of sonar equipment after the actual ship is delivered,and improve the measurement support capabilities of sonar equipment。
