Radar-centric DFRC Signal Design: Overview and Future Research Avenues

open access: yesLeida xuebao, 2023
During the confrontation of electronic systems, it is challenging to deal with the enemy’s comprehensive electronic weapons by simply combining electronic equipment, such as radar, communication, surveillance, and jammers. Hence, to meet the requirements

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 ...

Constrained Radar Waveform Design for Range Profiling [PDF]

open access: yesIEEE Transactions on Signal Processing, 2021
Range profiling refers to the measurement of target response along the radar slant range. It plays an important role in automatic target recognition. In this paper, we consider the design of transmit waveform to improve the range profiling performance of radar systems.

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 ...

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,

Deep Radar Waveform Design for Efficient Automotive Radar Sensing [PDF]

open access: yes2020 IEEE 11th Sensor Array and Multichannel Signal Processing Workshop (SAM), 2020
In radar systems, unimodular (or constant-modulus) waveform design plays an important role in achieving better clutter/interference rejection, as well as a more accurate estimation of the target parameters. The design of such sequences has been studied widely in the last few decades, with most design algorithms requiring sophisticated a priori ...

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.
