How to conduct electronic warfare in modern warfare?

The definition of electronic warfare is: tactics and techniques adopted to ensure one's own use of electromagnetic spectrum and prevent the enemy from using electromagnetic spectrum. The electromagnetic spectrum includes the frequency range from DC to light wave. Therefore, electronic warfare covers all frequency bands such as radio frequency spectrum, infrared spectrum, spectrum and ultraviolet spectrum. To put it bluntly, it is the suppression and anti-suppression of all electromagnetic waves. Among them, ESM is an electronic support measure and refers to the receiving part of electronic warfare; Electronic countermeasure is a kind of electronic countermeasure, which uses jamming, chaff and tracer to interfere with the normal work of radar and heat-seeking weapons. ECCM electronic countermeasures are various measures taken to suppress the influence of ECM in the design or work of radar or communication system. Now NATO countries recognized the definition of electronic warfare is:

Electronic warfare support ES-that is, traditional ESM electronic attack EA-includes traditional ECM, anti-radiation weapons, directed energy weapons (I have never understood why directed energy weapons are also included), and electronic protection EP-traditional ECCM.

Today, electronic warfare has become a part of wider information warfare.
