摘　　要：天线自动调谐是短波跳频通信中的关键技术之一 .提出一种高速天线调谐方案 ,并根据天线匹配网络元件参数与输入阻抗之间的圆网关系 ,提出一种快速调谐算法 .该算法已用于高速天线调谐器样机 ,在 1.6～ 30MHz波段内调谐时间小于 0 .5ms .The automatic antenna tuner is one of the key parts of SW frequency hopping (FH) communication system. In this paper, a rapid antenna tuner scheme as well as its tuning algorithm is presented. The practicability of this algorithm is verified by simulations. Based on the above work, a practical tuner has been successfully established. And the tuning time is less than 0.5 ms in the region of (1.6～30) MHz.
