压缩感知框架下的太阳图像重建方法
Research on the solar image reconstruction method based on compressive sensing
摘要
Abstract
One of the important goals of the developing antenna array of solar imaging is how to decrease the cell number of the array, due to the contradiction between limited budget and massive antennas. Inspired by the ability of compressed sensing to recover exactly the original signal from highly sub-Nyquist-rate samples and the sparse characters of solar image, this paper proposes a solar image reconstruction method based on the compressive sensing theory. The effectiveness of this scheme is illustrated by experiments of both simulated solar image and real astronomical image. Results show superiority of the proposed method in the resolution of the adjacent point source, the shape maintenance of the extanded source and the dynamic range.关键词
