Deceptive Jamming in WLAN Sensing [PDF]
2024 IEEE Radar Conference (RadarConf24)Joint Communication and Sensing (JCAS) is taking its first shape in WLAN sensing under IEEE 802.11bf, where standardized WLAN signals and protocols are exploited to enable radar-like sensing. However, an overlooked problem in JCAS, and specifically in WLAN Sensing, is the sensitivity of the system to a deceptive jammer, which introduces phantom targets

Deceptive Jamming Detection for SAR Based on Cross-Track Interferometry [PDF]
Sensors, 2018 Deceptive jamming against synthetic aperture radar (SAR) can create false targets or deceptive scenes in the image effectively. Based on the difference in interferometric phase between the target and deceptive jamming signals, a novel method for detecting deceptive jamming using cross-track interferometry is proposed, where the echoes with deceptive ...

A New Hybrid Method for Synthetic Aperture Radar Deceptive Jamming [PDF]
International Journal of Microwave Engineering, 2019 ABSTRACT Based on the synthetic aperture radar (SAR) geometric model, a novel, and fast algorithm of large scene deceptive jamming against different SAR systems is proposed. First, a template deceptive image is transformed into the time domain signal using inverse image formation algorithm.

Deceptive jamming against multi‐channel SAR‐GMTI [PDF]
The Journal of Engineering, 2019 Aimed at the problem that the deceptive jamming against synthetic aperture radar ground moving target indication generated by single jammer cannot work effectively in multi‐channel SAR, a novel deceptive jamming against multi‐channel SAR‐GMTI based on two jammers is studied. First, signal model of the novel deceptive jamming is built.

Deceptive Jamming Method with Micro-motion Property Against ISAR [PDF]
Radioengineering, 2017 Airborne target's micro-motion such as rotation or vibration causes phase modulation, termed as micro-Doppler effect, into radar signals. The feature of micro-motion is one of the most obvious features for radar recognition in mid-course phase. In traditional works, it is assumed that the micro-motion of the scatterer is the same as the ballistic ...

Multifrequency OFDM SAR in Presence of Deception Jamming [PDF]
EURASIP Journal on Advances in Signal Processing, 2010 Orthogonal frequency division multiplexing (OFDM) is considered in this paper from the perspective of usage in imaging radar scenarios with deception jamming. OFDM radar signals are inherently multifrequency waveforms, composed of a number of subbands which are orthogonal to each other.

Deception Jamming Against Doppler Beam Sharpening Radars [PDF]
2019 IEEE Radar Conference (RadarConf), 2019 Missile seekers are becoming increasingly more capable of using Doppler Beam Sharpening (DBS) modes as part of the homing cycle, which requires new countermeasures against this mode. One type of countermeasure, is to create false targets within the seeker DBS image. This paper proposes a jamming technique to generate false targets at a precise location

Three Decades of Deception Techniques in Active Cyber Defense -- Retrospect and Outlook [PDF]
Computers & Security, Vol. 106, 102288, Elsevier, 2021, 2021 Deception techniques have been widely seen as a game changer in cyber defense. In this paper, we review representative techniques in honeypots, honeytokens, and moving target defense, spanning from the late 1980s to the year 2021. Techniques from these three domains complement with each other and may be leveraged to build a holistic deception based ...
