An Effective Angle Deception Jamming Method

Monopulse radars have good anti-jamming ability against single point jamming.But the blinking jamming is an effective method against monopulse radars.Based on the analysis of the principle of angle tracking system of monopulse radars,the categories and efficiencies of blinking jamming are described.The study indicated that blinking jamming could make the radar antenna swing between two jamming sources,thus destroying the normal operation of angle tracking system of monopulse radars,and reducing the precision of weapon hitting the target.Finally,the jamming effects dependent on parameters were analyzed,and the selection principles of parameters were given.
