Abstract
A new method of SAR 2-D interrupted sampling repeater scatter-wave jamming is proposed.The jammer interruptedly samples the received SAR signal,and transmits interrupted-sampling SAR signal to ground.This jamming takes advantages of both the 2-D interrupted sampling jamming which can form multi-false targets,and the scatter-wave jamming which can make the jamming echo take the real targets' scattering information.This jamming method can realize two-dimensional jamming in range and azimuth,and cause the SAR image ambiguous.Its validities are proved by simulation.
