Compressed sensing and Sequential Monte Carlo for solar hard X-ray imaging. (arXiv:1812.08413v1 [astro-ph.SR])

We describe two inversion methods for the reconstruction of hard X-ray solar images. The methods are tested against experimental visibilities recorded by the Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI) and synthetic visibilities based on the design of the Spectrometer/Telescope for Imaging X-rays (STIX). 查看全文>>
