active jamming

active jamming
Electronic countermeasures in which an attempt is made to mask or suppress the enemy’s electromagnetic signals by high-powered radiation or re-radiation to impair the use of a specific band of frequencies. Self-protection jammers, stand-off jammers, and deception jammers are some of the devices used in active jamming. Self-protection jammers jam the radar receivers and thus make the task of detecting the target difficult. Stand-off jammers jam the enemy’s receivers from a safe distance. Deception jammers try to confuse the radar receivers.
