DOI: 10.1016/j.oceaneng.2020.107636
Abstract: Abstract Currently, the division of encounter situations and collision avoidance decisions both depend on the individual subjective judgment of officers under conditions of extraordinary complexity and randomness. Ambiguities and contradictions are present among the existing… read more here.

DOI: 10.1109/jsen.2025.3614305
Abstract: The azimuth resolution of real aperture radar (RAR) is limited by the effective beamwidth of the antenna. Based on the convolution relationship between target scatterings and the antenna pattern in the traditional model, the azimuth… read more here.

DOI: 10.1109/tgrs.2017.2737955
Abstract: Estimating azimuth offset with double-difference interferometric (DDI) phase, which is called multiple-aperture interferometric synthetic aperture radar (InSAR) or spectral diversity, is increasingly used in recent years to measure azimuth deformation or to accurately coregister a… read more here.

DOI: 10.1109/tgrs.2017.2783444
Abstract: State-of-the-art and future spaceborne synthetic aperture radar (SAR) systems increasingly often face the requirement of providing high-resolution images with reduced revisit times, requiring coverage of wide swaths. Since these are contradicting drivers in terms of… read more here.

DOI: 10.1190/tle36080677.1
Abstract: Abstract Most conventional 3D time-lapse (or 4D) acquisitions are ocean-bottom cable (OBC) or ocean-bottom node (OBN) surveys, as these surveys are relatively easy to replicate compared to towed-streamer surveys. To attain high degrees of repeatability… read more here.
