Deceptive jamming against multi‐channel SAR‐GMTI [PDF]
The Journal of Engineering, 2019 Aimed at the problem that the deceptive jamming against synthetic aperture radar ground moving target indication generated by single jammer cannot work effectively in multi‐channel SAR, a novel deceptive jamming against multi‐channel SAR‐GMTI based on two jammers is studied. First, signal model of the novel deceptive jamming is built.

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

One-bit splitting deceptive jamming against SAR
Defence Technology, 2022 One-bit quantization is a promising technique due to its performance retention and complexity reduction in a deceptive jammer against synthetic aperture radar (SAR). In this paper, the 1-bit quantization technology is utilized to agilely generate split false targets in the SAR imagery once the radar signal is intercepted, which reduces the complexity ...

A virtual actuator approach for the secure control of networked LPV systems under pulse-width modulated DoS attacks [PDF]
, 2019 In this paper, we formulate and analyze the problem of secure control in the context of networked linear parameter varying (LPV) systems. We consider an energy-constrained, pulse-width modulated (PWM) jammer, which corrupts the control communication ...

Quasi-Coherent Noise Jamming to LFM Radar Based on Pseudo-random Sequence Phase-modulation [PDF]
, 2015 A novel quasi-coherent noise jamming method is proposed against linear frequency modulation (LFM) signal and pulse compression radar. Based on the structure of digital radio frequency memory (DRFM), the jamming signal is acquired by the pseudo-random ...
