Radar Range Deception with Time-Modulated Scatterers [PDF]
, 2022 Modern radar systems are designed to have high Doppler tolerance to detect fast-moving targets. This means range and Doppler estimations are inevitably coupled, opening pathways to concealing objects by imprinting artificial Doppler signatures on the reflected echoes.

Radar Main-Lobe Jamming Suppression Based on Adaptive Opposite Fireworks Algorithm
IEEE Open Journal of Antennas and Propagation, 2021 In the presence of the main lobe jamming, the performance of the modern radar system would degrade significantly. In this study, a blind source separation (BSS) method based on an Adaptive Opposite Fireworks Algorithm (AOFWA) is proposed to address the ...

Anti-jamming Method for SAR Using Joint Waveform Modulation and Azimuth Mismatched Filtering [PDF]
arXiv, 2023 High-fidelity deception jamming can seriously mislead Synthetic Aperture Radar (SAR) image interpretation and target detection, which is difficult to identify or eliminate through traditional anti-jamming methods. Based on the Range-Doppler Algorithm (RDA), an anti-jamming method for SAR by using joint waveform modulation and azimuth mismatched ...

A Random Antenna Subset Selection Jamming Method against Multistatic Radar System [PDF]
, 2020 Multistatic radar system (MSRS) is considered an effective scheme to suppress mainlobe jamming, since it has higher spatial resolution enabling jamming cancellation from spatial domain. To develop electronic countermeasures against MSRS, a random array subset selection (RASS)jamming method is proposed in this paper.

Target Localization with Jammer Removal Using Frequency Diverse Array [PDF]
IEEE Transactions on Vehicular Technology ( Volume: 69, Issue: 10,
Oct. 2020), 2019 A foremost task in frequency diverse array multiple-input multiple-output (FDA-MIMO) radar is to efficiently obtain the target signal in the presence of interferences. In this paper, we employ a novel "low-rank + low-rank + sparse" decomposition model to extract the low-rank desired signal and suppress the jamming signals from both barrage and burst ...
