Activities used in EW include: electrooptical-infrared and radio frequency countermeasures; EM (electromagnetic) compatibility and deception, interference, intrusion and jamming, electronic masking, probing, reconnaissance, and intelligence, electronics security, EW reprogramming, emission control and spectrum management.
