Method of Implementing Scatter-wave Jamming Signal to SAR

Based on the process of the SAR signal propagation in space and the principle of scatter-wave jamming , a new realization method of scatter-wave jamming was provided , i.e. jamming by transmitting scatter-wave to SAR . By analyzing its mathematic model , it was testified that this jamming signal has the same mathematic model with jamming signal generated by transmitting original SAR signal directly to ground. This jamming method can realize two-dimensional jamming in range and azimuth, and cause the SAR image ambiguous. SAR image with jamming was generated by means of simulation processing of echoes with jamming signals, which was generated by the new method. The effect of the jamming methods was testified.
