Design of a Small Broadband Array System for High-Frequency Surface Wave Radar
岸基远程高频表面波雷达小型宽带天线系统的设计

According to the requirements of engineering design for High-Frcquency Surface Wave Radar (HF-SWR), at first, a small broadband transmitting antenna is optimized based on the theory of log periodic antennas. Then, based on the end-fire array theory, a small broadband twin-whip antenna with big forward to backward ratio is designed. And six twin-whip antennas are used as the fundmental element to form 12 side plane array system. The working principle of 12 side array and the log periodic antennas are analyzed, and calculating result is given in this paper. A practical broadband antenna system for HF-SWR is designed.
