An aperture synthesis system produces ringing at sharp edges and other transitions in the observed field. In this paper, we have developed an efficient multispectral deconvolution method, based on Split Bregman total variation minimization technique, and showed it to reduce image ringing, blurring, and distortion, while sharpening the image and preserving information content. We also present a multispectral...
An accurate geolocation of the radio frequency interference (RFI) sources is significant to effectively switch off illegal transmitters. In this study, utilizing the sparse property of RFI in the observed scene, a super-resolution RFI localization method based on compressive sensing is presented in synthetic aperture interferometric radiometer (SAIR). Numerical results show the presented method can...
This paper presents why the spatial resolution of an image captured by a plenoptic camera can be improved. The plenoptic camera captures the 4D light field (angular and spatial information of light) within a limited 2D sensor and results in reducing 2D spatial resolution due to inevitable 2D angular data. However, for improving the reduced resolution, we propose a novel analysis that 2D angular data...
