Abstract
To address the issue that in synthetic aperture radar(SAR)reconnaissance,passive jamming of tra-ditional rotating corner reflector exhibits a regular distribution pattern of jamming pixels in the azimuth direction resulting in its easy identification,this paper proposes a velocity-modulated rotating corner reflector array jam-ming method for SAR imaging.The proposed method performs sinusoidal modulation for the rotational speed of the corner reflectors,introducing a complex micro-Doppler modulation effect during the SAR imaging process,which enables the jamming pixels to present a wider span and more random distribution in the azimuth direction.Theoretical analysis and simulation results show that this method can effectively mask the protected target,and its jamming effect is superior to that of the conventional uniform rotation mode,thus providing theoretical support for anti-SAR reconnaissance of important targets and areas.关键词
