Deceptive Jamming Detection for SAR Based on Cross-Track Interferometry

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 ...

An Effective Method for Small Targets Detection in Synthetic Aperture Radar Images Under Complex Background

IEEE Access, 2022
Synthetic Aperture Radar (SAR) is a useful tool in marine surveillance. Small targets detection in SAR images especially in nearshore area is a difficult issue. Due to the complex background, there exist a lot of false targets.

Frequency-Enhanced and Multi-Scale Feature Fusion YOLOv11 for Low-Illumination Weak Projectile Target Recognition in Linear Array CCD Sensor

Sensors
To solve the problem where the low contrast and extremely small target size in the three-sky-screen target-integrated linear array CCD sensor measurement system under low-illumination conditions make it difficult to accurately identify projectile targets,

SAR deceptive jamming target-detection method based on multi-angle SAR images

The Journal of Engineering, 2019
Deceptive jamming is an effective jamming method for synthetic aperture radar (SAR). Time-delay repeater jamming, which is an important method of deceptive jamming because of its simplicity and effectiveness, can generate false targets in the SAR image ...

Consensus based target tracking against deception jamming in distributed radar networks

IET Radar, Sonar & Navigation, 2023
In this study, an anti‐deception jamming target tracking algorithm based on the data‐level fusion is proposed in a distributed radar network. First, the consensus covariance intersection (CCI) algorithm is proposed to improve tracking performance by ...

Empathy predicts false belief reasoning ability: Evidence from the N400 [PDF]

, 2014
Interpreting others’ actions relies on an understanding of their current mental state. Emerging research has begun to identify a number of factors that give rise to individual differences in this ability.

Website-Targeted False Content Injection by Network Operators

CoRR, 2016
It is known that some network operators inject false content into users' network traffic. Yet all previous works that investigate this practice focus on edge ISPs (Internet Service Providers), namely, those that provide Internet access to end users. Edge ISPs that inject false content affect their customers only.

Analysis of cooperative jamming against pulse compression radar based on CFAR

EURASIP Journal on Advances in Signal Processing, 2018
One important issue in radar jamming is the effect of inaccuracies in the radar position, which leads to a number of false targets entering the reference window of the constant false alarm ratio (CFAR) detector to reduce greatly.

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

FEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.
