中文摘要：

为降低经济成本，适应中小型渔船的需求，设计一种以FPGA为处理核心的通用雷达信号处理板。该信号处理板功能包括雷达信号的高速采集、实时运算、传输，并能处理来自GPS、电罗经、AIS、测深仪等外设信号。实现了雷达设备的小型化、模块化、通用化。实验结果表明，该信号处理板能快速接收雷达和外设信号并实时进行处理，符合未来船载雷达发展的趋势。

英文摘要：

To reduce the economic costs, and meet the requirement of the medium and small fishing boat, a universal ra- dar signal processing board based on FPGA was designed. The functions of the signal processing board include the high-speed data acquisition, transmission and real-time operation of radar signal, and the processing board can process the peripheral sig- nals from GPS, gyro compass, AIS and depth finder. The minimum, modularized and universal radar device was realized. The experimental results show that the signal processing board can quickly receive radar and peripheral signals, and process them in real time, which conforms to the development trend of the shipborne radar in the future.
