The evolution of electronic warfare has been driven by the competition between Electronic Countermeasures (ECM) and Electronic Counter-Countermeasures (ECCM). Electronic warfare involves not only harnessing the electromagnetic spectrum, but defending against enemy use of the spectrum, and, if possible, denying their ability to use it in the first place. Since the earliest attempts at jamming radio communications, techniques have been developed to counteract enemy ECM.
Intelligence-driven decision-making is at the heart of daily operations and strategic planning for modern militaries and intelligence agencies, and Signals Intelligence (SIGINT) is a big part of what makes it possible. Today we’ll discuss how SIGINT works and why it is so important, especially as it applies to Electronic Warfare applications.
