偶极子接收换能器驻波场校准系统的研究

A standing wave calibration system for dipole hydrophones

本文研究设计了偶极子接收换能器的驻波场校准系统，利用该系统可以实现偶极子类型接收换能器的校准，包括接收灵敏度及偶极子方向性的测量，频率范围为20－2000Hz，校准误差小于1dB．

A standing wave calibration system of dipole hydrophones has been developed. The receiving sensitivity and the directivity of dipole hydrophones with errors under 1dB are obtained by utilizing the system twer the frequency range from 20 to 2000Hz.
