摘　　要：作为鱼雷声自导子系统的水声信号采集系统由于信道容量的扩充,原硬件系统仅用DSP无法满足数据采集、处理的任务;为此引入FPGA(Filed Programmable Gate Array,现场可编程门阵列)负责系统底层硬件的控制和部分正交采样的计算任务;这样就减轻了DSP的负载,为充分发挥DSP的计算性能和今后算法升级提供了有利条件;文章详细介绍了FPGA在多通道数据采集、处理和传输中的设计思路和实现方法。Because of channel capacity expand, Underwater Acoustic signal collection system, the subsystem of homing system in torpedo, has met some problems. Its hardware system can not satisfy the task of data collection and data processing only with DSP. Therefore it leads into FPGA （Filed Programmable Gate Array） to take the responsibility. It can complete the data processing of system in part, and the control of systematic bottom hardware. This Hardware design have alleviated the load of DSP, is helpful to develop the calculation performance of DSP. Article has introduced the design idea and realization method on FPGA in some important functions of system in detail. These functions include multi-channel data collection, data processing and data upload,
