Description
Ionosphere influence practically excepts phase measurements at interferometric observations and leads to a "phase problem" in decameter radio astronomy. A tomographic approach to data processing based on use of the longitudinal correlation function as new information parameter at interferometric observations is proposed to solve an image reconstruction problem. It allows to reduce this problem up to a classical task of tomographic reconstruction on base of parallel projections. Such technique is less subject to influence of phase distortions. The developed tomographic procedure is being illustrated by results of numerical modeling with use of the experimental image of the CasA.
