Abstract:Based on the character of SAR imaging procedure, this paper proposes a new passive SAR barrage jamming approach, utilizing the rotating angular reflectors. This method makes use of micro-Doppler modulation induced by rotating angle reflectors in order to form jamming strips along azimuth and arrays of rotating angle reflectors to interfere SAR imaging in the range direction. Then, the targets can be covered effectively. In addition, the selection of the key parameter of the rotating angular reflectors is discussed in detail, and then a project of reflectors array is proposed. The results for both simulated and experimental?data have proved the validity of this method.
Keywords:Synthetic Aperture Radar(SAR)  Rotating angular reflector  Micro-Doppler modulation  Barrage jamming
