Electronic Warfare


measures taken to obtain information on the operating parameters and location of enemy electronic equipment (electronic reconnaissance), to impair or disrupt the operation of such equipment (electronic counter-measures), and to protect one’s own equipment from similar reconnaissance and countermeasures on the part of the enemy (electronic counter-countermeasures).

The mission of electronic reconnaissance is to detect enemy electronic equipment by its emission, determine its coordinates, and determine and analyze the characteristics of the signals it emits. This information is used in military intelligence and in the organization of electronic countermeasures.
