Moreover, an ADMM-based sparse method is introduced to recover the desired radar echoes using the estimated RFI parameters. Both simulated and experimental results are presented to demonstrate that our proposed algorithm outperforms the existing digital integration method, especially for severe RFI cases...
One-bit quantization is a promising technique due to its performance retention and complexity reduction in a deceptive jammer against synthetic aperture radar (SAR). In this paper, the 1-bit quantization technology is utilized to agilely generate split false targets in the SAR imagery once the rad...
Ultra-wideband radar cross-section reduction based on phase cancellation In this study, a 2-bit coding metasurface is proposed, which can achieve ultra-wideband radar cross section (RCS) reduction under arbitrary polarized incid... B Lin,W Huang,J Guo,... - 《Electromagnetics》 被引量: 0发表...
The diversity radar system consists of two frequency channels (A, B) connected to single-bit quantisers (1, 2). The outputs are combined in an OR-gate (3). The output signal of this is passed to a target extractor, which in this case is a travelling window detector. Unlike the ...

By integrating the unified model-based priors with data-driven learning, this work bridges the gap between theoretical guarantees and practical feasibility in one-bit single-snapshot DOA estimation, offering a scalable, hardware-efficient solution for next-generation radar and communication systems. 展开...
Direction-of-arrival (DOA) estimation [1,2,3,4,5,6] has attracted considerable attention in the field of array signal processing, and its applications to wireless communications, radar, and sonar are of substantial practical significance. A number of DOA estimation algorithms have been continuously...
