Study of Dynamic Calculating Model of SAR Jammer Protective Zone

According to the geometric relationship and technical characteristics of Synthetic Aperture Radar (SAR) electronic countermeasures (ECM),in this paper, a dynamic calculating model of jammer effective protective zone was established. The change law of jamming efficiency and effective protective zone under different jammer deployment was analyzed by simulation, and it provided some jammer deployment strategies in application. The dynamic model could calculate the size and location of effective protective zone with Air intelligence or aircraft track hypothesis, the results could guide jammer to choose a more scientific location deploy. At last this paper pass through research the distributing characteristic of effective protective zone under multiple operational tasks, put forward the multiple operational tasks calculation method of jammer effective protective zone.
