摘　　要：分别对甚低频发射天线的动态调谐电路与传统调谐电路进行了时域仿真,并在天线传输效率相同的条件下比较两者的输出波形及所需带宽。仿真结果表明,采用动态调谐技术的甚低频发射天线信号传输速率约是采用传统调谐技术的甚低频发射天线信号传输速率的1.33倍。This paper presents simulation and analysis for the synchronous turning system and traditional turning sys tem separately. The output amplitude and bandwidth are calculated for both sides on the same condition of the transmission rate The result of simulation demonstrated that： the transmission rate of signal of the synchronous turning system is 1.33 times of that of the traditional turning system.
