What is the definition of electronic warfare?

Electronic warfare is also called electronic countermeasures, including radio communication countermeasures, radar countermeasures and other photoelectric technologies and equipment countermeasures. Several local wars in recent years show that electronic reconnaissance, anti-reconnaissance, interference and anti-interference, confrontation and anti-confrontation have been widely used in the battlefield, and both sides are trying to seize the electromagnetic advantage to contain, weaken or even destroy the enemy's electronic countermeasures ability and win the final victory of the war.

Electronic warfare has gone through several stages of development, from communication countermeasure to radar countermeasure, and then to all-round confrontation of electronic weapon system. At all stages of development, the development of land, sea and air electronic warfare equipment and electronic countermeasures capability has always been the focus of countries' competition for electromagnetic superiority. In recent 20 years, due to the rapid development of large-scale integrated circuits and microcomputers, military electronic equipment is developing in the direction of miniaturization, good performance and low price, which provides a broad prospect for the wide use of electronic countermeasures equipment in modern wars. In modern warfare, almost every combat unit is equipped with electronic equipment and electronic countermeasures equipment. Electronic communication equipment, electronic detection equipment, such as warning radar, infrared night vision device, laser range finder, etc. ; Electronic communication equipment and communication jammer; Electronic warfare equipment such as automatic command and control has been widely used in modern warfare. In order to seize the initiative of electronic warfare, many countries have also set up electronic warfare forces.

Electronic reconnaissance equipment has made new breakthroughs in microelectronics, computer technology and photoelectric technology, and microcomputers have been widely used in various reconnaissance equipment: various reconnaissance equipment and equipment, far-infrared remote sensing detectors and laser equipment have been equipped in large numbers, and electronic reconnaissance technology has developed to a new stage of photoelectric reconnaissance.
