Annotation
The problem of reconstructing the two-dimensional distribution of electron concentration of the ionosphere in the plane of the orbit of a cluster of satellites is considered. Solution to the problem is be-lieved to allow for an operative monitoring of the ionosphere state. To solve the problem, a method of tomographic reconstruction of two-dimensional electron density distribution based on the convolution algorithm is proposed. The method includes three stages: formation of an initial approximation to the electron concentration; redefining the missing projection data in the radon image of a priori information about its form; application of the known convolution algorithm. Accuracy of the proposed method is analyzed using results of statistical modeling. The quality of recovery of small local disturbances is estimated.
