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

Physical Review E, 1995 We study a single-lane traffic model that is based on human driving behavior. The outflow from a traffic jam self-organizes to a critical state of maximum throughput. Small perturbations of the outflow far downstream create emergent traffic jams with a power law distribution $P(t) \sim t^{-3/2}$ of lifetimes, $t$.

Exploring the jamming transition over a wide range of critical densities [PDF]
, 2017 We numerically study the jamming transition of frictionless polydisperse spheres in three dimensions. We use an efficient thermalisation algorithm for the equilibrium hard sphere fluid and generate amorphous jammed packings over a range of critical ...

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
