recommendations! Published in 2024 at "Electronics Letters"

DOI: 10.1049/ell2.13201

Abstract: Radar coincidence imaging (RCI) is a high‐resolution radar imaging mode which constructs a temporal spatial stochastic radiation field (TSSRF) and uses the correlation between reference signal and echoes for imaging. The correlation between the reference… read more here.

DOI: 10.1063/1674-0068/cjcp2007119

Abstract: The recently constructed cryogenic cylindrical ion trap velocity map imaging spectrometer (CIT-VMI) has been upgraded for coincidence imaging of both ionic and neutral photofragments from photodissociation of ionic species. The prepared ions are cooled down… read more here.

DOI: 10.1088/1361-6463/adf231

Abstract: The capability of the random radiation frequency diverse metasurface aperture (FrDMA) determines the performance of the FrDMA based coincidence imaging (FrDMACI) system. However, there is still no theoretical analysis result, though the FrDMACI has been… read more here.

DOI: 10.1109/lgrs.2021.3127713

Abstract: In this letter, a novel microwave coincidence imaging (MCI) approach is proposed based on a multiple-input single-output (MISO) radar system to deal with the low signal-to-noise ratio (SNR) scenarios and off-grid problem. First, in coherent-detecting… read more here.

DOI: 10.1109/lmwc.2017.2769448

Abstract: A wideband frequency-polarization-diverse reflection aperture (WFPRA) for coincidence imaging is proposed in this letter. The reflection aperture is composed of polarization sensitive metamaterial cells with different resonant frequencies and different rotation directions. The cross-polarization information… read more here.

DOI: 10.1109/lsp.2022.3195085

Abstract: In this letter, a novel microwave coincidence imaging (MCI) method based on the attributed scattering model (ASM) is proposed. Unlike the classical MCI model which assumes the target as a set of discrete scatterers, the… read more here.

DOI: 10.1109/tgrs.2018.2810145

Abstract: The spatial modulation coincidence imaging (SMCI), as a novel kind of microwave coincidence imaging method, is proposed in this paper. The SMCI system provides a new way to produce the time-space independent signal instead of… read more here.
