Recent studies indicate the potential of low frequency space-borne SAR sensors to monitor and quantify structure and dynamics of ionosphere [1–3]. At the post-sunset sector of the equatorial ionosphere, the instability of the electron density often induces plasma bubbles aligned to the geomagnetic field [4], whose effects are seen as distinctive stripe patterns on SAR data [5–6]. At the same time,...
In this paper we propose some ionospheric correction schemes for space-borne synthetic aperture radar (SAR) and polarimetric interferometric SAR (PolInSAR). The spatial and temporal variation of the free electron density in the upper-most atmosphere affects the propagation of the radar pulse resulting in image distortions. We estimate the total electron content (TEC) by applying the Appleton-Hartree...
