Deceptive jamming against multi‐channel SAR‐GMTI [PDF]

open access: yesThe 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.

One-bit splitting deceptive jamming against SAR

open access: yesDefence Technology, 2022
One-bit quantization is a promising technique due to its performance retention and complexity reduction in a deceptive jammer against synthetic aperture radar (SAR). In this paper, the 1-bit quantization technology is utilized to agilely generate split false targets in the SAR imagery once the radar signal is intercepted, which reduces the complexity ...

Mixed jamming suppression algorithm for phased array radar

open access: yesThe 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 ...

Modelling Strategic Deceptive Planning in Adversarial Multi-Agent Systems [PDF]

open access: yesarXiv, 2021
Deception is virtually ubiquitous in warfare, and should be a central consideration for military operations research. However, studies of agent behaviour in simulated operations have typically neglected to include explicit models of deception. This paper proposes that a computational model that approximates the human deceptive planning process would ...

DeepFake: Deep Dueling-based Deception Strategy to Defeat Reactive Jammers [PDF]

open access: yesarXiv, 2020
In this paper, we introduce DeepFake, a novel deep reinforcement learning-based deception strategy to deal with reactive jamming attacks. In particular, for a smart and reactive jamming attack, the jammer is able to sense the channel and attack the channel if it detects communications from the legitimate transmitter.

Phase Characteristics and Angle Deception of Frequency-Diversity-Array-Transmitted Signals Based on Time Index within Pulse

open access: yesRemote Sensing, 2023
The transmitted beam of frequency diversity array (FDA) has the range–angle–time coupling property, which has essential applicative potential in angle deception and active anti-jamming. In this paper, the concept of time index within pulse is introduced.

A New Hybrid Method for Synthetic Aperture Radar Deceptive Jamming [PDF]

open access: yesInternational 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.
