Abstract

Abstract

The conventional correction method based on invariable TEC is no longer applicable to GEOSAR, because the temporal variability of ionosphere exits in synthetic aperture time of GEOSAR. In this paper, a correction method based on 4-D electronic density is put forward. This method is validated using actual data of ionosphere and the results indicate that this method can correct the ionospheric effects induced by temporal variability on GEOSAR effectively.
