摘　　要：在对跳扩频通信的研究中,采用软件无线电技术实现数字相关器,比较起用模拟器件实现相关算法具有灵活性和稳定性,调试也更加方便。在经过算法推导后,给出了仿真结果,从理论上奠定了实现的基础。然后在DSP+FPGA的架构上介绍了算法实现的流程图。最终实际做出的模块根据实测结果达到了设计要求。做出的模块也应用在超短波扩频电台中。实践证明这是一款实用的实现方法。When research in FH/DS radio communication,the paper implements a digital correlator by technology of software defined radio. The digital correlator is more flexible and stable than analog design,and easier to debug. It illustrates the algorithm and shows the result of simulate by computer. It is proved the possible to implement. Then, introduces the flow chart of the implementation of algorithm on the imbed system of DSP＋FPGA. It achieves the desire of the design in real module. It is practiced on the FH/DS radio and is proved as a practicality means.
