中文摘要：

体积庞大、结构复杂的水声仪器设备往往在使用和维护等方面给使用者带来不便，因此对于水声设备的小型化要求已经必不可少。水声时间反转应答系统是水声时间反转镜研究的主体设备。论文结合水声信道匹配研究的实验要求，以MSP430F169微控制器作为核心部件，设计了一种适用于水声时间反转镜研究的小型化、低功耗应答系统。文中给出了详细的硬件及软件设计方案，以及该系统的应用原理。该设计体积小巧、结构简练，在保证性能的前提下，极大地提高了系统的易用性和灵活性。

英文摘要：

Equipments used for underwater acoustics research usually have large size and complicated structure, which is inconvenient for application and maintenance. So the miniaturization of the equipments becomes necessary. Underwater acoustics time reversal responder system is the major equipment for the research on underwater acoustics time reversal mirror. According to the experiment requirement, a responder system with small size and low power consumption is designed. The kernel component of the system is MSP430F169 microcontroller. The hardware and software designs are presented, and the application and function of the system are also introduced. This design improved the convenience and flexibility of the system with small size and concise structure, while ensuring the performance.
