摘要
针对甚低频发信系统工作性能的研究,建立了甚低频发信系统仿真模型,利用模型对甚低频电子管发信系统工作在假负载模式、天线模式、固定调谐方式及动态调谐方式分别进行了仿真计算,分析了不同方式、不同载频及不同码元速率下的系统传输性能。计算结果表明甚低频发射天线动态调谐系统具有比固定调谐方式传输效率高,系统允许的信息传输速率可得到大幅提高。
For the performance research of VLF transmitting system, the simulation model of VLF transmitting system is established and used for the simulation and analysis of the performance of VLF transmitting system operating in dummy load mode,antenna mode, fixed tuning mode and dynamic tuning mode.The transmission performance of the system in different modes and at different frequencies and symbol rates is analyzed.The results show that the transmission efficiency of synchronous turning system is higher than that of tradi- tional turning system.The information transmission rate allowed by the system can be improved greatly.
