Research on deceptive jamming technologies against SAR

2009 2nd Asian-Pacific Conference on Synthetic Aperture Radar, 2009
Synthetic aperture radar (SAR) has its own special features different from conventional radar. It has high processing gain, so jamming to SAR is more difficult than that to conventional radar. Jamming to SAR finds its important usage in some military scene.

Primary exploration on ISAR image deception jamming

2007 1st Asian and Pacific Conference on Synthetic Aperture Radar, 2007
This article puts forward theoretical model on ISAR deception jamming by theoretical analysis, including space model and jamming signal model. Space model includes location relation and movement relation between radar, target and jamming platform, jamming signal model based on the relation between jamming signal and radar signal, distance migration of ...

Velocity deception jamming discrimination using quantization effect

Analog Integrated Circuits and Signal Processing, 2019
In this letter, the effects of number of quantization levels are studied in the airborne digital radio frequency memory (DRFM). The artificial signal, produced by DRFM, has quantized amplitude that results in different cross-correlations (with respect to the real target echo signal), when correlated by continuous reference signal.

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.

Optimized Application Of Multi-UAV Electromagnetic Deception Jamming

2020 IEEE 4th Information Technology, Networking, Electronic and Automation Control Conference (ITNEC), 2020
The confrontation between group UAV cooperation and netted radar is always the focus of the game in the field of electronic warfare. In this paper, the model of multi UAV cooperative jamming netted radar system is studied, and the optimization model of how to generate false track by using the least number of UAVs is analyzed in detail to implement the ...

Study of multistatic radar against velocity-deception jamming

2011 International Conference on Electronics, Communications and Control (ICECC), 2011
Compared with monostatic radar, multistatic radar has considerable merits against deception jamming because its transmitting system and receiving system are separated physically. Firstly velocity-deception jamming styles and their working principles are introduced in brief. Then a new type of multistatic radar that consists of one transmitter and three

Analysis of Active Deception Jamming Model against SAR

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 ...

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

Multi-receiver deception jamming against synthetic aperture radar

2016 CIE International Conference on Radar (RADAR), 2016
In practical situation, it is difficult to obtain precise electronic surveillance for the non-cooperative targets. Thus the deception modulation which lies deeply on the electronic surveillance would be easy to be identified. In the purpose to modify the parameters dependence, this paper proposes a new deception jamming algorithm based on the ...
