Abstract:

Operating in an orbit with an altitude of approximately 36000 km, Geosynchronous Synthetic Aperture Radar (GEO SAR) can achieve large-scale (thousands of kilometers) and quick revisit (less than 24 hours) observations towards scenes of interest. Therefore, compared with low-earth-orbit (LEO) SAR, it is considered a promising spaceborne sensor for disaster monitoring. In the past several years, in-depth studies regarding system design, imaging algorithms, atmospheric effects, interferometric processing et al., have been conducted. Especially, a GEO SAR was just launched by China on 13 August 2023. This section is focused on latest research progress on GEO SAR theory, algorithms, data processing and in particular, the GEO SAR mission, which will show a significant prospect on this promising Earth observation sensor.
