Theory and Design of Blink Jamming

Applied Sciences, 2020
Establishing an error in the angle estimates of a monopulse radar is critical to creating miss distance during the terminal stage of missile engagements. However, the tools for creating angle deception are limited, with blink jamming offering significant

Radar Main-Lobe Jamming Suppression Based on Adaptive Opposite Fireworks Algorithm

IEEE Open Journal of Antennas and Propagation, 2021
In the presence of the main lobe jamming, the performance of the modern radar system would degrade significantly. In this study, a blind source separation (BSS) method based on an Adaptive Opposite Fireworks Algorithm (AOFWA) is proposed to address the ...

UNIDECOR: A Unified Deception Corpus for Cross-Corpus Deception Detection [PDF]

arXiv, 2023
Verbal deception has been studied in psychology, forensics, and computational linguistics for a variety of reasons, like understanding behaviour patterns, identifying false testimonies, and detecting deception in online communication. Varying motivations across research fields lead to differences in the domain choices to study and in the ...

Adaptive Dual-Polarization Filtering Method for Countering Active Jamming

International Journal of Antennas and Propagation, 2020
In order to counter active jamming, an adaptive polarization filtering method based on dual polarization radar is put forward. First, the signal flow principle of the dual polarization radar and its signal model are introduced.

OFDM-based JCAS under Attack: The Dual Threat of Spoofing and Jamming in WLAN Sensing [PDF]

This study reveals the vulnerabilities of Wireless Local Area Networks (WLAN) sensing, under the scope of joint communication and sensing (JCAS), focusing on target spoofing and deceptive jamming techniques. We use orthogonal frequency-division multiplexing (OFDM) to explore how adversaries can exploit WLAN's sensing capabilities to inject false ...

Cyber Deception for Computer and Network Security: Survey and Challenges [PDF]

arXiv, 2020
Cyber deception has recently received increasing attentions as a promising mechanism for proactive cyber defense. Cyber deception strategies aim at injecting intentionally falsified information to sabotage the early stage of attack reconnaissance and planning in order to render the final attack action harmless or ineffective.

Deception Jamming for Squint SAR Based on Multiple Receivers

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2015
A deception jamming method for synthetic aperture radar (SAR) based on multiple receivers is proposed. This method deals with the parameters of hostile SAR as a whole for deception jamming. By measuring the range differences between different receivers, higher accuracy can be achieved than detecting each of the parameters directly.
