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

Radar Waveform Design and the Heisenberg Group
Applied 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.

Deep Radar Waveform Design for Efficient Automotive Radar Sensing [PDF]
2020 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 ...

Constrained Radar Waveform Design for Range Profiling [PDF]
IEEE 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.

Multi-Target Robust Waveform Design Based on Harmonic Variance and Mutual Information
Advances in Mathematical Physics, 2020 Cognitive radar is an intelligent radar system, and adaptive waveform design is one of the core problems in cognitive radar research. In the previous studies, it is assumed that the prior information of the target is known, and the definition of target ...

Phase retrieval for radar waveform design
Information and Inference: A Journal of the IMAAbstract The ability of a radar to discriminate in both range and Doppler velocity is completely characterized by the ambiguity function (AF) of its transmit waveform. Mathematically, it is obtained by correlating the waveform with its Doppler-shifted and delayed replicas.

Multi-Beam Radar Communication Integrated System Design
Information, 2023 In this paper, we propose a multi-beam integrated radar and communication scheme using phased-array antenna, in which the same LFM-BPSK integrated waveform is used for both the radar and the communication beams.

Space‐Time Coding Conformal Metasurfaces for Multifrequency Beam Steering and Shaping
Advanced Materials, EarlyView.Space‐time coding conformal metasurfaces enable dynamic wave control on curved surfaces by combining programmable spatial patterns with temporal modulation. This study shows that a single conformal aperture can independently manipulate multiple frequency components, achieving multifunctional beam shaping and steering, with implications for ...
