DOI: 10.1109/lgrs.2021.3107438
Abstract: High-quality waveform decomposition, as one of the most critical cores of light detection and ranging (LiDAR) data processing, has become increasingly interesting. However, the current Gaussian decomposition method cannot handle the superimposed waveform with only… read more here.

DOI: 10.1109/tgrs.2024.3427852
Abstract: Due to the large imaging scene of geosynchronous synthetic aperture radar (GEO SAR), multiple ship targets are more likely to appear in the same imaging scene. When the targets overlap in the range dimension, their… read more here.
