DOI: 10.1109/lgrs.2017.2678987
Abstract: This letter presents a new scheme for ground moving target indication in high-resolution wide-swath (HRWS)-synthetic aperture radar (SAR) systems. The asymmetry of the Doppler spectra is measured to extract the range bins with moving targets.… read more here.

DOI: 10.1109/taes.2022.3187386
Abstract: High-resolution and wide-swath imaging serves as an important task for synthetic aperture radar (SAR). However, the tradeoff between high azimuth resolution and wide unambiguous swath coverage has not been well optimized in traditional SAR system.… read more here.

DOI: 10.1109/tgrs.2020.3023472
Abstract: In the context of spaceborne synthetic aperture radar (SAR) imaging, high resolution and wide swath are inherently conflicting requirements. These may, however, be simultaneously satisfied by advanced imaging modes with multichannel architectures in elevation and/or… read more here.

DOI: 10.1364/oe.468880
Abstract: High three-dimensional (3D) resolution for a wide field-of-view (FoV) is difficult in LiDARs because of the restrictions concerning size, weight, and power consumption (SWaP). Using a static unitary detector (STUD) approach, we developed a photodetector… read more here.
