Ionospheric Tomography technology is computer tomography technology , suitable for large-scale spatial distribution of monitoring ionospheric electron density and its disturbance ionospheric sounding . In this paper, the use of Ionospheric Tomography technology ionospheric electron density distribution of the inversion , the main tasks are as follows : 1 , CT inversion theory ionosphere system discussion , focusing on Ionospheric inversion algorithm the realization of retrieval errors have been investigated , proposed the mixed inversion method based on image reconstruction optimization algorithm . 2 , the use of IRI2001 reference model of the ionosphere MART algorithm and the proposed hybrid algorithm was simulated inversion MART inversion results with the hybrid algorithm inversion results were compared , the results show that the new algorithm can be improved to a certain extent the quality of image reconstruction . 3, the measured GPS-TEC data provided by IGS (International GPS Service) Ionospheric Tomography inversion analysis of the characteristic parameters of the ionosphere variation with latitude , altitude , time , and inversion results vertical probe data were compared. 4 ionosphere occultation , and the use of two-dimensional ray tracing technology to simulate a the occultation ray propagation path .
