Abstract:

This paper studies the jamming technology of synthetic aperture radar(SAR) based on digital radio frequency memory(DRFM) coherent suppression jamming technology, and 2D area target jamming technology based on target echo simulated technology. These two kinds of jamming technologies use jamming signals highly related to radar radiation signals, which have the characteristics of high coherent degree. This paper first discusses the echo data model of SAR radar point target and area target, and then discusses the principles of DRFM coherent suppression jamming technology and 2D area target jamming technology respectively. Finally, the DRFM suppression jamming technology and area target jamming technology are simulated by using Matlab. At the same time, together with the traditional noise suppression jamming technology, the jamming effect is compared and analyzed, and the application suggestions of jamming technology are given. The simulation results show that area target jamming is more effective of SAR image spot jamming. DRFM coherent suppression jamming technology is suitable to SAR image of large bandwidth and high resolution, and area target jamming is more widely used in SAR deception jamming.

Key words: synthetic aperture radar (SAR), digital radio frequency memory (DRFM), correlation suppression jamming, area target jamming
