摘要：
Synthetic aperture radar(SAR) dual-channel cancellation technique can suppress various kinds of jamming signals including the scatter-wave jamming signals, so utilizing the azimuth intermittent sampling scatter-wave jamming method to counter the dual-channel cancellation system via slow-time intermittence is put forward.First, the SAR dual-channel cancellation principle of scatter-wave jamming is derived.Then the azimuth intermittent sampling scatter-wave jamming model is built, and its jamming performance to traditional SAR is analyzed.Next, its jamming performance to SAR dual-channel cancellation system in two kinds of phase compensation conditions is studied.Theoretical analysis and experiment results show that, when the phase estimated by the automatic phase searching algorithm is used, this jamming method can produce chaotic dark and bright speckles and false scattering scenes in the scene cancellation imaging; when the exact phase is used directly, this jamming method can produce multi-false scattering scenes and cancellation dark stripes. © 2018, Chinese Institute of Electronics.
