Changes in Transmitting-Receiving Characteristics of Underwater Acoustic Transducer by Transformer

트랜스포머에 의한 수중 음향 트랜스듀서의 송수신 특성의 변화

In this study, the changes in transmitting and receiving characteristics, especially resonance frequencies, of the underwater acoustic planar array transducer by the transformers used in the analog weighting circuit are investigated. Electrical equivalent circuit analysis shows that an ideal transformer does not change the resonance frequency of the transmitting mode, but the resonance frequency which gives the maximum receiving sensitivity can be designed by adjusting the magnitude of reactance of transformer.
