SAR Seeker Deception Jamming and Anti-jamming Measures [PDF]

2019 6th Asia-Pacific Conference on Synthetic Aperture Radar (APSAR), 2019
Considering repeater jamming for anti-ship SAR seeker, this paper proposes a mathematical model of repeater jamming for SAR. The influence of parameter estimation accuracy on the effectiveness of repeater jamming is analyzed. In the end, several anti-jamming measures of SAR seeker are summarized in anti-ship scenario.

Mitigation of Jamming Attacks via Deception

2020 IEEE 31st Annual International Symposium on Personal, Indoor and Mobile Radio Communications, 2020
This paper considers the problem of mitigating jamming attacks by aiming to deceive the jammer. Specifically, in the presence of a jammer, to defend a transmitter-receiver pair sending (real) information, the paper proposes the novel technique of sending fake information over a second transmitter-receiver pair in order to deceive the jammer into ...

Strategy Optimization for Range Gate Pull-Off Track-Deception Jamming Under Black-Box Circumstance

IEEE Transactions on Aerospace and Electronic Systems, 2023
In this article, we study the strategy optimization problem of black-box range gate pull-off (RGPO) jamming. In the black-box RGPO jamming, the jammer does not have extensive knowledge about the tracking model of the threat radar, which makes it ...

Research on deception jamming for countering ISAR

IET Conference Publications, 2009
This paper establishes a mathematical model of deception jamming for countering inverse synthetic aperture radar (ISAR). Based on this model, we analysis the condition in which successful deception jamming will be realized when using max correlation and Doppler centroid tracking (DCT) for motion compensation. Simulation results validated the analysis. (
