Jamming a terahertz wireless link
Nature Communications, 2022 As the demand for bandwidth in wireless communication increases, carrier frequencies will reach the terahertz (THz) regime. One of the common preconceived notions is that, at these high frequencies, signals can radiate with high directivity which ...

CHI '14 Extended Abstracts on Human Factors in Computing Systems, 2014 Recent years have witnessed a rise in Game Jams - organized events to create playable prototypes in a very short time frame. Game Jams offer a unique and quick way to prototype games. Beyond that, we believe Game Jams can also be seen as a design research method, situated in the research-through-design tradition, to create knowledge in a fast-paced ...

Radar Anti-Jamming Decision-Making Method Based on DDPG-MADDPG Algorithm
Remote Sensing, 2023 In the face of smart and varied jamming, intelligent radar anti-jamming technologies are urgently needed. Due to the variety of radar electronic counter-countermeasures (ECCMs), it is necessary to efficiently optimize ECCMs in the high-dimensional ...

Jamming Bandits—A Novel Learning Method for Optimal Jamming [PDF]
IEEE Transactions on Wireless Communications, 2016 Can an intelligent jammer learn and adapt to unknown environments in an electronic warfare-type scenario? In this paper, we answer this question in the positive, by developing a cognitive jammer that adaptively and optimally disrupts the communication between a victim transmitter–receiver pair.

DRFM-Based Repeater Jamming Reconstruction and Cancellation Method with Accurate Edge Detection
Remote Sensing, 2023 Digital radio frequency memory (DRFM) based repeater jamming can create false targets, which can lead to a loss of situational awareness, misidentification of targets, and decreased overall performance of the radar system. Traditional jamming suppression

Jamming in granular polymers [PDF]
Physical Review E, 2011 We examine the jamming transition in a two-dimensional granular polymer system using compressional simulations. The jamming density ϕ_c decreases with increasing length of the granular chain due to the formation of loop structures, in excellent agreement with recent experiments.

Mixed jamming suppression algorithm for phased array radar
The Journal of Engineering, 2019 The most common type of mixed jamming is composed of blanket jamming and deception jamming. In order to effectively detect the target signal in this kind of mixed jamming, this study presents an algorithm based on side-lobe cancellation (SLC) and slope ...

Performance Analysis of Multiple Antennas Synthetic False Target Jamming
IEEE Access, 2022 The radar jamming technology has been studied in this paper mainly, which uses the antenna synthetic wave to generate phase distortion at the signal reception to carry out angle measuring jamming, such as traditional cross-eye jamming. However, cross-eye
