Rayleigh resolution limit
WebApr 16, 2024 · Conventional beamforming technique suffers from the Rayleigh resolution limit and can't obtain high resolution DOA estimation. To solve this problem, we propose a new Bayesian Compressive Sensing model based on Generalized Cauchy distribution family and develop a novel DOA estimation method. To exhibit superior performance in sparse … WebIn semiconductor lithography, the Rayleigh criterion for resolution determines just how small the transistors on a microchip can be. ...

WebFeb 15, 2024 · Every imaging system has a resolution limit, typically defined by Rayleigh's criterion. Given a fixed number of photons, the amount of information one can gain from an image about the separation between two sources falls to zero as the separation drops below this limit, an effect dubbed ``Rayleigh's curse.'' Recently, in a quantum-information- …
