Abstract: An autofocus method was presented based on an entropy criterion for synthetic aperture radar imaging. An iterative method, through minimizing the entropy ...
Abstract: Correct and robust translational motion compensation is necessary but challenging for inverse synthetic aperture radar (ISAR) imaging and target recognition. On the one hand, parametric ...
The first-ever full-frame anamorphic lenses with autofocus are here – but the Sirui Astra series has more than one unusual feature. First introduced on Kickstarter, the Sirui Astra series is now ...
