| Reverberation, especially short range reverberation which occurs after emission signal, is primary interference for the active sonar, consumedly limits the operation distance and parameter estimate of the active sonar, but sometimes the short range reverberation is difficult to collect. So it is necessary to design the Reverberation Data Acquisition System to collect the reverberation signal.The main task of this paper is based on the needs of the reverberation experiment in designing a suitable binary vector array reverberation data acquisition measurements experimental apparatus, which includes the two parts of underwater acoustic power transmitter design and debugging and multi-channel data acquisition system design and commissioning.Underwater acoustic signal power transmitter is composed of five parts: the signal source modules, digital signal processing, power amplifier module, power modules and matching networks. This paper researches the basic theory. It combines the designing principles and experience of modern audio power amplifier. It applies the digital audio power amplifier technology to the design of underwater acoustic transmitter, which will effectively simplify the designing difficulty and reducing the designing costs of underwater acoustic transmitter power.Multi-channel reverberation data acquisition system is mainly composed of power board, analog receiver boards and control board. It can put the functions like mixed-signal receiving, zooming, filtering, collecting and uploading into practice. The equipment can be powered by 220-volt AC power supply, it adopts low-power, low-noise, wide band and wide dynamic range design, which is able to achieve real-time signal display and functions such as automatic gain control. This paper also combines the inherent characteristics of the reverberation signal. It adopts a unique anti-saturation control circuit design, which is effective to solve the problem of collector signal blocking in signal acquisition process.
