In this paper, a GEOSAR mission with typical LEOSAR parameters but longer integration time to increase the received power is presented. Such systems can provide images of large areas with continuous monitoring. The revisit time is reduced to the synthetic aperture integr ation time to reach the desired resolution and SNR require- ments. However, the Atmospheric Phase Screen (APS) ar tefacts must be characterized to compensate the long term atmospheric phase decorrelation. An APS correc tion methodology from short term periodic acquisitions (sub-apertures) of the whole long term synthetic aperture is analysed. Finally, the first results obtained from Ground-Based SAR (GB-SAR) real data are presented to validate the proposed correction method.
