Hybrid Domain Efficient Modulation-Based Deceptive Jamming Algorithm for Nonlinear-Trajectory Synthetic Aperture Radar

open access: yesRemote Sensing, 2023
Deception jamming of synthetic aperture radar (SAR) has attracted extensive attention due to its low power consumption and high fidelity advantages. However, existing SAR deception jamming algorithms assume that SAR operates on a linear trajectory.

Deceptive jamming suppression in multistatic radar based on coherent clustering [PDF]

open access: yesJournal of Systems Engineering and Electronics, 2018
This paper proposes a suppression method of the deceptive false target (FT) produced by digital radio frequency memory (DRFM) in a multistatic radar system. The simulated deceptive false targets from DRFM cannot be easily discriminated and suppressed with traditional radar systems.

A Novel Chaotic-NLFM Signal under Low Oversampling Factors for Deception Jamming Suppression

open access: yesRemote Sensing, 2023
Synthetic aperture radar (SAR) is a high-resolution imaging radar. With the deteriorating electromagnetic environment, SAR systems are susceptible to various forms of electromagnetic interference, including deception jamming. This jamming notably impacts

A New Hybrid Method for Synthetic Aperture Radar Deceptive Jamming [PDF]

open access: yesInternational Journal of Microwave Engineering, 2019
ABSTRACT Based on the synthetic aperture radar (SAR) geometric model, a novel, and fast algorithm of large scene deceptive jamming against different SAR systems is proposed. First, a template deceptive image is transformed into the time domain signal using inverse image formation algorithm.

Adaptive Countering Technique for Angle Deception Based on Dual Polarization Radar Seeker

open access: yesInternational Journal of Antennas and Propagation, 2017
Angle deception jamming makes the monopulse radar seeker track to itself but not the real target, which is catastrophic for the guidance radar. In this paper, an adaptive technique based on dual polarization radar is presented to counter it.

Game Theory Design for Deceptive Jamming Suppression in Polarization MIMO Radar [PDF]

open access: yesIEEE Access, 2019
Controlling the polarization states of transmit waveforms can improve the performance of radar systems, especially for main lobe jamming suppression applications. In this paper, we consider the design of optimal transmit polarizations for deceptive jamming suppression in the main lobe using a game theory framework.

Intelligent Recognition of Chirp Radar Deceptive Jamming Based on Multi-Pulse Information Fusion [PDF]

open access: yesSensors, 2021
The perception of jamming types is very important for protecting our radar in complex electromagnetic environments. Radar active deceptive jamming based on digital radio frequency memory (DRFM) has a high coherence with the target echo, which confuses the information of the target echo and achieves the effect of hiding the real target.
