According to the requirements of data bus transfer rate for multi-frequency HF ground wave radar,this paper designed a data transmission system based on Ethernet communication. The system which has employed a digital signal processor TMS320C6748 with a 10 /100 Mb·s- 1adaptive Ethernet interface can both handle a large number of radar sampling data and communicate with the host computer directly without additional hardware platform. This system has the following functions: setting the fixed and variable IP address,receiving and uploading device information,responding to online equipment search commands and uploading radar sampling data regularly. At the same time the system provides a series of effective reliability test plans. Test results show that the network communication system has a good stability and reliability,and the data transfer rate can be up to an average of 80 Mb / s,which meets the needs of the multi-frequency HF ground wave radar system very well. 多频高频地波雷达 TMS320C6748 以太网 可靠性测试 multi-frequency HF ground wave radar TMS320C6748 Ethernet reliable test 10.14188/j.1671-8836.2015.05.010 TN958 国家自然科学基金资助项目（40976105,41376182）;国家海洋局数字海洋科学技术重点实验室开放基金（KLD0201401）;国家博士后科学基金（2013M531738）;中央高校基本科研业务费专项资金资助项目（274020,114003,2042014kf0028）;海洋公益性行业科研专项重大项目（201205032）;湖北省科技支撑计划项目（2014BEC057） 2015-05-01 2021-03-31 5 61
