Analysis on Influence of Synchronous Blinking Jamming to Radar Seeker Antenna

Synchronous blinking jamming is an effective countermeasure against radar seeker. It causes line-of-sight angle to step continuously between the two angular positions through jamming resources emit by turns. Seeker antenna always adjusts to track the line-of-sight angle in synchronous blinking jamming, so the oscillation of antenna is produced. According to angle tracking circuit model of radar seeker, the relation between the parameters of jamming resource and seeker antenna is studied. In the end, the antenna response curves is simulated in different jamming parameters.
