Radar High-Speed Target Coherent Detection Method Based on Modified Radon Inverse Fourier Transform

IEEE Transactions on Aerospace and Electronic Systems, 2023
Within the long-time coherent integration (CI) in radar detection, the range walk effect inevitably impacts high-speed targets, which makes coherent detection methods invalid. To address this problem, a coherent detection method, a modified radon inverse

Water-Based Coherent Detection of Broadband Terahertz Pulses.

Physical Review Letters, 2022
Both solids and gases have been demonstrated as the materials for terahertz (THz) coherent detection. The gas-based coherent detection methods require a high-energy probe laser beam and the detection bandwidth is limited in the solid-based methods ...

Chaotic Optical Communication Over 1000 km Transmission by Coherent Detection

Journal of Lightwave Technology, 2020
Chaotic optical communication was originally proposed to provide high-level physical layer encryption. For high-speed and long-distance transmission, chaotic signal is very sensitive to channel impairments such as dispersion and Kerr fiber nonlinearity ...

Computationally efficient coherent detection and parameter estimation algorithm for maneuvering target

Signal Processing, 2019
In this paper, a computationally efficient coherent detection and parameter estimation algorithm via symmetric autocorrelation function (SAF) and scaled Fourier transform (i.e., SAF-SFT) is proposed, involving range cell migration (RCM) and Doppler ...
