Electronic jamming is a form of electronic warfare where jammers radiate interfering signals toward an enemy's radar, blocking the receiver with highly concentrated energy signals. The two main technique styles are noise techniques and repeater techniques. The three types of noise jamming are spot, sweep, and barrage. 웹Robustness of Adaptive Narrowband Beamforming ... - IEEE Xplore . Robustness of Adaptive Narrowband Beamforming ... - IEEE Xplore
