A Method against Interrupted-Sampling Repeater Jamming Based on Energy Function Detection and Band-Pass Filtering [PDF]
International Journal of Antennas and Propagation, 2017 Interrupted-sampling repeater jamming (ISRJ) is a new kind of coherent jamming to the large time-bandwidth linear frequency modulation (LFM) signal. Many jamming modes, such as lifelike multiple false targets and dense false targets, can be made through ...

Suppression Method for Main-Lobe Interrupted Sampling Repeater Jamming in Distributed Radar
IEEE Access, 2020 Main-lobe interrupted-sampling repeater jamming is a coherent type of interference. As this interference is injected through the main lobe of the antenna into a radar system, the interference heavily degrades the performance of the radar system.

Orthogonal phase-frequency coded signal in a pulse against interrupted sampling repeater jamming
The Journal of Engineering, 2019 Interrupted sampling repeater jamming (ISRJ) uses the under sampling technology to transmit and repeat the radar intercepted signals. As a new kind of coherent interference, it is widely used in self-defence interference.

Waveform Domain Adaptive Matched Filtering for Suppressing Interrupted Sampling Repeater Jamming
IEEE Transactions on Aerospace and Electronic Systems, 2023 The inadequate adaptability to flexible interference scenarios remains an unresolved challenge in the majority of techniques utilized for mitigating interrupted-sampling repeater jamming (ISRJ). Matched filtering system based methods is desirable to incorporate anti-ISRJ measures based on prior ISRJ modeling, either preceding or succeeding the matched ...
