FAST DECEPTIVE JAMMING AGAINST TOPSAR

IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
Terrain observation by progressive scans synthetic aperture radar (TOPSAR) is a novel two dimensional imaging mode with wide swath coverage. However, it will cause problems when our regions of interest are being detected by hostile TOPSAR. To prevent this threaten from TOPSAR, this paper presents a corresponding deceptive jamming method by taken the ...

SAR Seeker Deception Jamming and Anti-jamming Measures

2019 6th Asia-Pacific Conference on Synthetic Aperture Radar (APSAR), 2019
Considering repeater jamming for anti-ship SAR seeker, this paper proposes a mathematical model of repeater jamming for SAR. The influence of parameter estimation accuracy on the effectiveness of repeater jamming is analyzed. In the end, several anti-jamming measures of SAR seeker are summarized in anti-ship scenario.

Micro-Doppler Deception Jamming for Tracked Vehicles

IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
As tracked vehicles play significant roles in a battlefield, effective jamming measures is necessary to protect them from being perceived by hostile radar. Moving tracked vehicles exhibit strong Doppler and micro-Doppler signatures. Therefore, the jamming signal should include micro-Doppler modulation generated by metallic caterpillars for successful ...

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.

Deceptive jamming suppression with frequency diverse MIMO radar

Signal Processing, 2015
Simulated false targets cannot be easily discriminated and suppressed with traditional radar systems, especially for the mainbeam deceptive jamming. In this work, we explore the multiple-input multiple-output (MIMO) radar with frequency diverse array (FDA) as the transmit array and study its ability to suppress the deceptive jamming in joint transmit ...

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.
