Abstract: | Applying the technique of computer tomography to ionosphere detection, Computerized Ionospheric Tomography (CIT) can produce
the large scale distribution of electron density in a two dimentional longitudinal section of ionosphere. According to the
actual detecting condition of sparse receiver and limited projecting angle, polynomial interpolation method and projecting
angle expansion method are proposed. A new energy function is formulated according to the constraint of least neighbourhood
error. Simulated annealing is incorporated in the iteration of ART to get the global minimum of energy function.
