Research on deception jamming for countering ISAR

IET Conference Publications, 2009
This paper establishes a mathematical model of deception jamming for countering inverse synthetic aperture radar (ISAR). Based on this model, we analysis the condition in which successful deception jamming will be realized when using max correlation and Doppler centroid tracking (DCT) for motion compensation. Simulation results validated the analysis. (

SAR deceptive jamming signal simulation

2007 1st Asian and Pacific Conference on Synthetic Aperture Radar, 2007
Based on SAR jamming geometry model and radar waveform, the signal model on SAR deceptive jamming is presented, and the simulation method which is feasible in project is verified. The jamming signal is produced to protect single point or multi-points target, and is validated by SAR imaging algorithm.

Countermeasure for Smart Jamming Threat: A Deceptively Adversarial Attack Approach

ICC 2021 - IEEE International Conference on Communications, 2021
With the development of software-defined radio (SDR) and artificial intelligence (AI), smart jammers are becoming more and more powerful, and have cognitive and intelligent capacities such as spectrum sensing, learning and reconfigurability. To cope with the AI-enabled smart jammers, this paper investigates the naive weakness of smart jamming ...

A Novel Anti-Deceptive Jamming Method for Multistatic SAR

IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019
Multistatic synthetic aperture radar (SAR) have achieved significant performance in the field of anti-jamming for its flexible configuration. Hence, its capacity of anti-jamming is very important in electronic warfare. In addition, it is difficult to remove the false targets caused by the deceptive jammer from SAR echoes.

A Blanket Deception Jamming Rejection Approach Based on Jamming Sample Recognition

2007 International Conference on Microwave and Millimeter Wave Technology, 2007
Blanket deception jamming is characteristic of both noise jamming and deception jamming, which cause some traditional anti-jamming measures invalid such as sidelobe canceling and sidelobe blanking and so on. In this work, an approach of time-space cascade adaptive sidelobe canceling based on jamming sample recognition is presented. Even when the number

The Effect of Jamming/Deception on Decision Making

1984
Abstract : The present experiment examined the capability of developing a simulation methodology for assessing the effects of Command, Control, and Communications CounterMeasures (C3CM) on a human operator. Primarily, the effects on human information jamming and deception were applied against a key decision maker in a simulated, air defense, C3 system ...

Study on target pose and deception jamming to ISAR

2009 2nd Asian-Pacific Conference on Synthetic Aperture Radar, 2009
The quality of ISAR (Inverse Synthetic Aperture Radar) imaging is closely related to the target pose and its motion law. Only high range resolution can be achieved, whereas can not in azimuth in some occasions. However, two-dimensional high resolution images of pre-selected target can be formed if ISAR is decoyed effectively.

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
