摘　　要：为解决传统短波模拟电台训练系统无法对天波传输环境进行模拟的问题,提出了一种将天波链路传输模型与传统短波模拟电台训练系统相结合的方法。该方法根据用户设置的时间、经纬度、天线类型、电台类型等参数,计算得到“频率窗”,系统将用户设置的通信频率与“频率窗”比较,选频的好坏最终体现在模拟电台的通信话音质量。天波传输模型的引入相较于传统短波模拟电台训练系统,更接近真实使用环境,训练效果更加明显,对用户实操更具指导意义。In order to solve the problem that the traditional shortwave analog radio training system can not simulate the skywave transmission environment,a method of combining the skywave link transmission model with the traditional shortwave analog radio training system is proposed.This method calculates the"frequency window"based on the time,latitude,longitude,antenna type,radio type and other parameters set by the user.The system compares the communication frequency set by the user with the"frequency window".The quality of frequency selection is ultimately refl ected in the communication voice quality of analog radio stations.Compared with the traditional shortwave analog radio training system,the introduction of skywave transmission model is closer to the real use environment.The training effect is more obvious and the practical operation of users is more instructive.
