NDLI: Mosaic scene deception jamming based on 2D separation modulation against SAR

Content Provider	IET Digital Library

Abstract	The false scene, which is formed by the false scene deception jamming signal, can cover the real target and scene, confuse synthetic aperture radar (SAR), and mislead the decision-making. If an area is selected to be protected by utilising the false scene deception jamming, the computational burden of the jammer is related to the number of false scatterers. An important problem faced by the SAR deceptive jammer is how to generate the false scene with the low computational burden. To overcome this disadvantage, a mosaic scene deception jamming based on two-dimensional separation is proposed against SAR. The intercepted SAR signal is separated and retransmitted in azimuth and range to enlarge the width of the main lobe and generate the ‘mosaic scene’, which reduces the resolution of the false targets to fill the protected area. Therefore, the number of false scatterers is decreased and the computational burden is also reduced. Moreover, to make a low-resolution false scene similar to the real scene and ensure the jamming effectiveness, the mosaic scene deception jamming template should be highly correlated with the false scene deception jamming template. Finally, the validity of the proposed method is verified by the simulation results.
