摘要：

A novel composite repeating jamming method for synthetic aperture radar (SAR) is proposed, which combines in-pulse separation and reordering with interpulse intermittent sampling subtly. The basic idea is as: firstly storing the SAR pulse completely, then separating, reordering the stored signal, finally transmitting the stored signal in the next one or several pulse repetition periods to the radar. Based on the signal models of SAR, principles of the jamming are derived. Then, the relationship between key jamming parameters and the effect is analyzed. Furthermore, the conclusion is verified via simulation. The result shows that the jamming can produce two-dimensional deceptive jamming or suppression jamming according to well configured the key jamming parameters.
