In the last three decades, the great powers have become increasingly dependent on satellite communication (SATCOM), very high frequency (VHF), and ultrahigh frequency providing high bandwidth line-of-sight communications. These military communication channels lack resilience because an electronic warfare (EW) campaign can affect both VHF and SATCOM simultaneously. The 1940s preferred spectrum, high frequency, with its different propagation patterns, offers an opportunity for military communication resiliency in the 21st century. The concept of retrograding could give an operational advantage and create the ability to sustain communication in EW saturated environment.

逆向通信的弹性-短波作为军事通信渠道的复兴

在过去的三个十年中，大国越来越依赖于提供高带宽视距通信的卫星通信 (SATCOM)、甚高频 (VHF) 和超高频。这些军事通信渠道缺乏弹性，因为电子战 (EW) 活动可以同时影响甚高频和卫星通信。1940 年代首选频谱、高频及其不同的传播模式，为 21 世纪的军事通信弹性提供了机会。逆行的概念可以提供作战优势，并创造在电子战饱和环境中维持通信的能力。
