| Abstract: | Repeater jamming is an effective means to Synthetic Aperture Radar(SAR). In this paper, the principle of the SAR repeater jamming is introduced, and the positions and imaging quality of the illusory targets are also discussed. Meanwhile, considering the signal processing time in the practical engineering, the feasibility of the received signal's delay repeating is also studied. Simulation result confirms the conclusions derived from above, and a practical use of the repeater jamming is introduced at last. |
