Abstract: The dipole emitter transducer is the core component of the remote acoustic logging instrument. The energy and working bandwidth of the sound wave radiated by the sound source directly affect the quality of the logging data. In this paper, the mechanical and electrical equivalent model of the transducer is combined with the broadband impedance matching network, and the network component parameters are calculated based on the adaptive Gauss-Newton algorithm, which can fully consider the material and structure parameters of the transducer and achieve rapid convergence. Finally, a sound field test is carried out in the anechoic pool, where the active power, excitation voltage, horizontal directivity, and hydrophone receiving voltage at the transducer end are observed simultaneously. The effect of the impedance matching network is comprehensively evaluated, which provides a reference for the subsequent research and development of dipole acoustic logging instruments and experimental testing. The experimental results show that the broadband impedance matching network designed in this paper can significantly improve the acoustic radiation performance of the transducer, broaden the bandwidth by 3 times, and increase the active power by 2.7 times.
