What does the term 'electromagnetic spectrum' refer to in Electronic Warfare?

The term 'electromagnetic spectrum' refers to the range of all electromagnetic radiation, encompassing all frequencies from low-frequency radio waves to high-frequency gamma rays. In the context of Electronic Warfare, understanding the electromagnetic spectrum is crucial because it allows military personnel to utilize, manipulate, and protect against various forms of electromagnetic energy.

This involves intelligence gathering through signals, jamming enemy communications, and ensuring the effectiveness of one’s own communication systems by operating effectively within the spectrum. Mastery of the electromagnetic spectrum enables military forces to dominate battlefield communication and information systems while also disrupting adversaries' capabilities, which is fundamental to successful operations in modern warfare.
