Analysis of deception jamming to ISAR imaging system

2007 1st Asian and Pacific Conference on Synthetic Aperture Radar, 2007
This paper presents a method of deception jamming to ISAR imaging system (Chen and Andrews, 1980). By series of simulations we will prove that when real target and fake target are moving in different trace the jamming is available and practical.

A Method of Counteracting Main Lobe Deception Jamming with Frequency Diverse Array

2023 6th World Conference on Computing and Communication Technologies (WCCCT), 2023
In this paper, a jamming nulling method to counteract the deception jamming of the main lobe is studied. The radar adopts the frequency diverse array transmitting mode and the phased-array receiving mode.

A Deception Jamming Approach Based on Four-Dimensional Antenna Arrays

IEEE Asia-Pacific Conference on Antennas and Propagation, 2023
A novel deception jamming method based on the scattering mechanism of four-dimensional (4-D) antenna arrays is proposed in this paper. The scattered echo signal can be dynamically regulated by the periodic modulation of switches, thus a part of scattered

An Effects Evaluation Method for Angle Deception Jamming

2009 First International Conference on Information Science and Engineering, 2009
An effects evaluation method for angle deception jamming was discussed. Based on the analysis of combat capacity of aircraft and weapon system, when the distance between radar and jammer is equal to the minimal shooting distance, the relation between the signal-to-jamming ratio at the radar input and the radar angle tracking error was obtained, and the

Analysis of Active Deception Jamming Model against SAR [PDF]

Advanced Materials Research, 2014
The limitations of basic active deception jamming model against SAR reconnaissance were analyzed detailed, and the necessary conditions of false target deployment for the model were derived. Some modifications and adjustment of the basic model were made, for which target-centric signal transmission schedule was proposed instead of jammer-centric ...

Anti-Deception Jamming Resource Scheduling for Multitarget Tracking in Distributed Radar Networks

IEEE Transactions on Aerospace and Electronic Systems
In this article, we propose an anti-deception jamming joint radar-to-target assignment and power scheduling (ADJ-JRAPS) strategy in distributed radar networks to discriminate the false target and achieve multitarget tracking (MTT) under deception jamming.

Deception jamming modeling in radar sensor networks

MILCOM 2008 - 2008 IEEE Military Communications Conference, 2008
In this paper we create a modeling scenario which includes an airborne imaging radar platform, receiving platform and an electronic countermeasure (ECM) platform whose goal is to introduce false target images. We also assume a high-resolution stripmap SAR model operating with several common types of UWB signals, as well as the newly proposed OFDM radar

PSPNet: Pretraining and Self-Supervised Fine-Tuning-Based Prototypical Network for Radar Active Deception Jamming Recognition With Few Shots

IEEE Geoscience and Remote Sensing Letters
To address the problems of requiring a large number of labeled training jamming samples in practical applications, we propose the PSPNet, an improved prototypical network with pretraining and self-supervised fine-tuning, which can achieve high-precision ...
