摘　　要：论文针对甚低频通信特点,从甚低频辐射天线的性能入手,分析了甚低频传输信道限制信号高速传输的瓶颈问题,提出了一种基于固态开关器件的动态调谐技术及其实现方法,并基于该方法建立了原理验证模型,通过研究两种不同的开关控制策略,以此分析出适用于甚低频通信信道的信号传输方法,最后通过对移频信号的仿真和小容量功率等级的验证试验,证明了该方法在窄带网络下高速传输信号的可行性。In view of the characteristics of very low frequency communication,this paper analyzes the bottleneck problem of high-speed transmission of very low frequency transmission channel limiting signal from the performance of very low frequency radiating antenna,and proposes a dynamic tuning technology based on solid state switching device and its implementation method.Based on this method,a principle verification model is established. By studying two different switch control strategies,the signal transmission method suitable for the very low frequency communication channel is analyzed. Finally,the simulation of the frequency shift signal and the verification test of the small capacity power level are carried out. It proves the feasibility of this method to transmit signals at high speed under narrowband networks.
