In this paper, with a view to neutralize the guided missile, effectiveness of jamming Electronic Attack (EA) technique, which is applied by helicopter platform, on miss distance is analyzed. The missile, which has infrared seeker and 3D PPN guidance model, is modeled as a point-mass. This missile is also equipped with last value and linear extrapolation Electronic Protection (EP) against jamming EA technique carried out by platform. As a result of analysis, the increasing of seeker tracking error and jamming duration increase the miss-distance. In addition, last value EP is more effective than linear extrapolation with regards to missile.
