| 摘要: |
| 甚低频(VLF)电波传播过程中因环境因素影响会使信号产生衰减与扰动,导致潜艇收信可靠性下降.文中基于传播媒质环境地-电离层参数的统计预测,运用波导模式理论对甚低频电波的信号场强进行预测,为甚低频对潜通信系统在运行中调整其可变参数或在特定参数条件下避开传播衰减与扰动提供传播环境服务,使通信系统工作性能与信道特性达到良好匹配,从而实现提高对潜通信效能的目的. |

| () |
| Abstract: |
| The signal will have attenuation and disturbance due to environmental factors in the process of VLF radio wave propagation, which will impact the reliability of submarine communication. This paper discusses the method of predicting the field strength of VLF radio based the statistics prediction of earth - ion- osphere parameters, offers the service of propagation environment for the system to adjust the variable parameters or abstain from propagation attenuation, makes the system performance matching the channel character and advancing the effects of submarine communication. |
| Key words: VLF communication submarine communication radio wave propagation field strength prediction |
