| 传统高频地波雷达接收机与天线阵列由长电缆连接，存在成本高、架设难、不易维护等问题。本文提出了一种新体制的高频地波雷达系统，该系统将多通道接收机分为多个装配在接收机天线附近的独立的单通道接收单元，接收单元与天线之间采用短电缆连接模式，各个接收单元之间通过GPS/北斗进行时钟同步，通过无线方式进行参数配置和数据传输。在完成单通道接收单元设计与实现后，通过闭环实验和海边现场实验对整个新系统进行了检测，得到了稳定的海洋回波，证明了新体制雷达系统的可行性。 |

| Abstract: |
| The receiver of the traditional high frequency (HF) surface wave radar (SWR) was usually connected with the receiving array by long cables, which may increase the cost and difficulty of the installation and maintenance for the radar system. A novel HF SWR system is introduced in this paper. The receiving module of this system composes of several independent single-channel receiving units mounted near the receiving antennas, and a short cable connection mode is used between the receiving unit and the antenna. The clock synchronization between each receiving unit is realized through GPS/BDS, and parameter configuration and data transition for the radar system are achieved through wireless transmission. The new radar system has been checked through the closed-loop experiments and field experiments and has received stable sea echoes, which demonstrates the feasibility of the proposed radar system. |
