Abstract. We investigate the capabilities of the back-propagation and radio-holographic methods for the interpretation of data of radio occultation sounding of ionospheric perturbations in regions of sporadic E-layers. Several occultations of Microlab-1 satellite are analysed, where multipath propagation from E-layers is detected. It is shown that the back-propagation technique can be used for processing radio occultation data in multipath zone in order to derive vertical profiles of the refraction angle. The holographic technique allows for the detection of complicated horizontal structures of ionospheric inhomogeneities, where the standard Abel inversion technique cannot be used for the derivation of vertical profiles of electron concentration.
