| 摘 要： | 介绍了短波通信的特点,分析了短波地波传播过程中引起衰减的重要因素。短波地波通信时,对不同距离、频率条件下的接收点场强进行了计算。引入噪声干扰对接收点的信噪比进行计算,进而可以确定编队内部短波通信频率选择范围。分析频率选择范围是保证通信质量和持续时间的基础,对于提高编队内部短波通信效率有重要意义。

| Abstract: | HF communication is an important communication means among the formation. This paper introduces the characteristic of HF communication,and analyses main factors causing HF terra wave attenuation,and also counts received signal intensity of HF terra wave communication for different distance and frequency. Yawp jam is considered,and received SNR is achieved. At last,frequency scope of HF communication among the formation is ascertained. The analysis of frequency scope is the foundation to guarantee communicat... |
