A disc transducer embedded circular transducer is used to achieve transceiver integration, with the external circular transducer transmitting the signal and internal disc transducer receiving the reflected signal. The resonance frequencies of the two circular transducers are theoretically analyzed, and the formula for calculating the receiving sensitivity of the disc transducer is theoretically derived. Finite element simulation software is used to determine the thickness of the internal disc hydrophone （receiving transducer）, and its radius is adjusted to change the area ratio to analyze the effect of different area ratios on the transceiver performance. The results show that the transceiver transducer has a maximum transmit voltage response of 177 dB and receive sensitivity of -166 dB when the area ratio is 0.2.
