一、前言预报出适应电离层变化的工作频率,是保证短波通信的关键。作者曾根据电离层参数随地磁纬度变化的相关规律,利用电离层观测站的实时观测资料采用内插或外推技术,对给定的短波通信电路进行提前一天的短期频率予报,予报较准,使用效果较好。为了向众多的短波通信用户提供更有效的频率予报手段,本文给出利用全国九个电
I. Foreword Predicting how to adapt to changes in ionospheric frequencies is the key to ensuring short-wave communications. According to the correlation law of ionospheric parameters with the change of geomagnetic latitude, the author used the interpolation or extrapolation techniques of real-time observational data of ionospheric stations to report the short-term frequency of a given short-wave communication one day in advance, Quasi, the use of better. In order to provide a more efficient frequency to many shortwave communication users to report means, this paper gives the use of nine national power
