Airborne Radar Anti-Jamming Waveform Design Based on Deep Reinforcement Learning

open access: yesSensors, 2022
Airborne radars are susceptible to a large number of clutter, noise and variable jamming signals in the real environment, especially when faced with active main lobe jamming, as the waveform shortcut technology in the traditional regime can no longer ...

Online unsupervised generative learning framework based radar jamming waveform design

open access: yesIET Radar, Sonar & Navigation, 2023
The jamming effect on radar is dominated by the design of the jamming waveform directly. Traditional jamming waveforms are generated using the template‐based method and are not environmentally resilient. Without the precise radar centre frequency support,

Extended Target Recognition in Cognitive Radar Networks

open access: yesSensors, 2010
We address the problem of adaptive waveform design for extended target recognition in cognitive radar networks. A closed-loop active target recognition radar system is extended to the case of a centralized cognitive radar network, in which a generalized ...

Radar Waveform Design and the Heisenberg Group

open access: yesApplied and Computational Harmonic Analysis, 1995
The paper under review is in the spirit of a recent paper on the deformation theory of radar ambiguity functions published by the same authors [Weyl multipliers. J. Fourier Anal. Appl. 2, 191-215 (1995)]. It begins with a presentation of the Heisenberg group theoretic setting [\textit{W. Schempp}, Radar reception and nilpotent harmonic analysis. I--IV.
