短波通信系统以其设备简单、造价低廉、通信距离大、机动性强和易于组网等优点,成为一种用于军事及民用通信的手段。然而,短波信道受电离层衰落、多径效应,自然界和人为干扰的影响以及频谱拥挤等一系列问题限制了它的使用范围。本文对如何使短波通信适应近代电子对抗的需要进行了探讨,其中短波跳频通信是一种可行的途径。 The shortwave communication system has become a means for military and civilian communications due to its simple equipment, low cost, large communication distance, strong mobility and easy networking. However, the shortwave channel is limited in scope by a series of problems such as ionospheric fading, multipath effects, the effects of natural and man-made interference, and spectrum congestion. This article discusses how to adapt shortwave communications to modern electronic warfare. The shortwave frequency hopping communication is a feasible way.
