Holding a virtual monopoly in a product on which the artificial intelligence boom relies should be a golden ticket. For chipmaker Nvidia, it has been. But ASML, which makes extraordinarily complex ...

We introduce a novel synthetic-aperture imaging method for radar systems that relies on sources of opportunity. We consider receivers that fly along arbitrary, but known, flight trajectories and ...

The sleek hull of the USS Arkansas (SSN 800) slid into the James River on July 2, 2025, marking a significant milestone in the U.S. Navy’s relentless pursuit of undersea dominance. Built by Huntington ...

A 1.4x teleconverter will reduce the maximum aperture of the lens by a full f-stop, while a 2x teleconverter cuts it by two full stops. So if you have a 300mm f/2.8 lens, adding a 1.4x converter will ...

Two delay-and-sum beamformers for 3-D synthetic aperture imaging with row-column addressed arrays are presented. Both beamformers are software implementations for graphics processing unit (GPU) ...
