During the first two world wars, the forces quickly understood the benefits of mastering enemy communications, and with the help of scientists and industrialists, they quickly conceived, developed and implemented techniques not only to intercept communications, but also to carry out appropriate, meticulous counter-operations.
From then on, as the world became more and more connected and networked military action strategies developed, electronic warfare became an unavoidable reality.
Electronic Warfare (EW) utilizes all the technologies allowing the mastery and control of the electromagnetic spectrum to carry out military actions.
As a reminder, the electromagnetic spectrum is the range of electromagnetic waves, from gamma rays to radio waves related to their wavelength, their frequency or even their energy. Only a narrow part of this spectrum is in the visible domain. So just like the sea, land, air and space, it has become a battlefield theater.
