Analysis of active noise jamming against synthetic aperture radar ground moving target indication

The rapid development of Synthetic Aperture Radar Ground Moving Target Indication (SAR-GMTI) is threatening ground moving targets. The key against it is the efficient jamming technology. This paper introduces SAR-GMTI at first. Then, RF noise jamming, noise AM jamming, noise FM jamming and noise convolution jamming are also introduced and analyzed. Finally this paper illustrates the jamming effect by computer simulation which contains velocity estimation and detection probability. The results show that under the proper JSR condition, the active noise jamming can jam SAR-GMTI effectively, and under the same JSR condition, noise convolution jamming has a more efficient jamming effect than those non-coherent jamming obviously.
