摘要

采用ICECAP高频传输预测软件对指定海区消耗型短波通信浮标与岸基多台站之间的通信电路进行仿真分析,计算了最高可用频率、信噪比和浮标鞭状天线的场强分布。分析了天线的场强覆盖,计算出场强中值大于接收机灵敏度的台站个数。在满足信噪比要求及频率低于MUF的条件下,选择可通信台站多的频率作为长期可用工作频率。该方法给短波通信的选频提供了一个更加直观的途径。
A communication circuitry between the short-wave expendable communications buoy and shore receivers is analysed by ICECAP HF propagation model and the field intensity of the buoy antenna,SNR and MUF is simulated.On the basis of analysing the field intensity,the number of the receivers which the field intensity median is bigger than the valve of receiver.When the SNR is satisfied and the frequency is lower than MUF,the frequency by which the most receiver can communication is selected as the working frequency.Such a method is more intuitionistic for short-wave frequency selection.
