    Abstract
  • The ionospheric irregularities have important impact on the satellite navigation, communication, radar system etc. In this paper, the numerical simulation and observation data contrast are both carried out to validate the feasibility of wavelet decomposition and reconstruction method. Taking sporadic E for example, in numerical simulation, the background of the electron density distribution is simulated by the International Reference Ionosphere (IRI). Then the horizontal total electron density (δht) is used in the inversion of the ionosphere irregularities, and the results are compared with the simulated data. With the wavelet decomposition and reconstruction method of observation data, the COSMIC occultation data from 1 to 9 in July 2009 have been compared with the ground-based observation data provided by SPIDR. Both results show well accordance with the true value or observation which indicates the method is feasible for the inversion of ionosphere irregularities. This is in great significance for the research of ionosphere irregularities.
