Ionospheric tomography: its limitations and reconstruction methods

Web1 mei 2015 · Ionosphere tomography is a typical ill-posed problem, and using the ionosphere priori information as the constraints to improve the state of normal equation is an effective approach to solve this problem. In this paper, we impose priori constraints by increasing the virtual observations in $n$-dimensional space.
