Deception Jamming Against Doppler Beam Sharpening Radars [PDF]

2019 IEEE Radar Conference (RadarConf), 2019
Missile seekers are becoming increasingly more capable of using Doppler Beam Sharpening (DBS) modes as part of the homing cycle, which requires new countermeasures against this mode. One type of countermeasure, is to create false targets within the seeker DBS image. This paper proposes a jamming technique to generate false targets at a precise location

Consensus based target tracking against deception jamming in distributed radar networks [PDF]

IET Radar, Sonar & Navigation, 2023
AbstractIn this study, an anti‐deception jamming target tracking algorithm based on the data‐level fusion is proposed in a distributed radar network. First, the consensus covariance intersection (CCI) algorithm is proposed to improve tracking performance by introducing the consensus theory to the field of covariance intersection fusion.

Fast target deception jamming method against spaceborne synthetic aperture radar based on equivalent bistatic scattered fields [PDF]

The Journal of Engineering, 2019
To achieve verisimilar target deceptive jamming effect, the jamming signals from different targets in different kinds of situation must be acquired. However, it is difficult to be implemented by the methods using deception-template model. In this letter,

Time-varying metasurface driven broadband radar jamming and deceptions

Optics Express
Conventional radar jamming and deception systems typically necessitate the custom design of complex circuits and algorithms to transmit an additional radio signal toward a detector. Consequently, they are often cumbersome, energy-intensive, and difficult to operate in broadband electromagnetic environment.

Advances in Anti-Deception Jamming Strategies for Radar Systems: A Survey [PDF]

arXiv
Deception jamming has long been a significant threat to radar systems, interfering with search, acquisition, and tracking by introducing false information that diverts attention from the targets of interest. As deception strategies become more sophisticated, the vulnerability of radar systems to these attacks continues to escalate.

Method for four‐channel monopulse radar to resist dual‐source angle deception jamming [PDF]

The Journal of Engineering, 2019
Towed decoy can simulate the time domain and frequency domain characteristics of target in radar beam and form effective angle deception. In order to improve the radar ability to countermeasure towed decoy, this study extracts and uses the radar diagonal difference channel in the conventional monopulse radar.

A Parameter Estimation-Based Anti-Deception Jamming Method for RIS-Aided Single-Station Radar

Remote Sensing
Multi-station radar can provide better performance against deception jamming, but the harsh detection requirements and risk of network destruction undermine the practicability of the multi-station radar.

Improved method for synthetic aperture radar scattered wave deception jamming

IET Radar, Sonar and Navigation, 2014
This study presents an improved scattered wave jamming method for synthetic aperture radar (SAR). The jammer adjusts the time‐delay and the phase of the intercepted SAR signal. Then, a false scene is created to provide an effective protection for a certain area.
