An Improved Interrupted Sampling Repeater Jamming to SAR
Applied Mechanics and Materials, 2011A new kind of Synthetic Aperture Radar (SAR) jamming method is proposed: the 2-D interrupted-sampling repeater jamming. The fundamentals and implement of this jamming method are investigated. This jamming method can realize two-dimensional jamming in range and azimuth, and cause the SAR image ambiguous, and achieves the effect of multi-false targets ...

Multi-level quantization method for suppressing interrupted-sampling repeater jamming
International Conference on Signal Image Processing and Communication (ICSIPC 2021), 2021Interrupted-sampling repeater jamming, which is a new type of coherent jamming based on digital radio frequency memory can produce dense false target groups. According to the idea of ‘reconstruction and cancellation’, the paper uses multilevel quantization method to generate a large number of local templates to match the actual jamming, then the ...

A novel parameter estimation method of interrupted sampling repeater jamming
2019 IEEE International Conference on Signal, Information and Data Processing (ICSIDP), 2019Interrupted sampling repeater jamming(ISRJ) is an effective coherent jamming type for wideband chirp radar. Different parameter settings correspond to different jamming strategies, and the generated false target jamming can achieve effects of both deception and suppression.

Energy Function Guided Histogram Analysis for Interrupted Sampling Repeater Jamming Suppression
2022Interrupted sampling repeater jamming (ISRJ) is a novel intra-pulse coherent jamming based on digital radio frequency memory (DRFM). By repeatedly sampling and retransmitting the radar transmitting signal fragments, a series of false targets can be formed after pulse compression (PC), posing a severe threat to modern radar systems.

Research on sampling duty ratio in interrupted sampling repeater jamming
Interrupted sampling repeater jamming (ISRJ) is an effective jamming method in modern electronic countermeasures, but its sampling duty ratio (SDR) should be no more than 50%. This paper proposes a distributed interrupted sampling repeater jamming solution to settle this problem based on the basic principle of the ISRJ. The simulation results show thatJianchi Qi +3 more
