Title:Research progress on geosynchronous SAR system analysis and information processing in China

Abstract: The geosynchronous SAR (GEO SAR) runs on a geosynchronous orbit at a height of 36000 km, which has a certain inclination and thus is not geostationary. The relative movement between GEO SAR and ground targets can be obtained to achieve two-dimensional SAR imaging. Compared with the traditional low Earth orbit SAR (LEO SAR), GEO SAR has irreversible advantages of short revisit period (several hours), large observation coverage (hundreds to thousands of kilometers), etc.

However, the orbit height of GEO SAR increase by two orders of magnitude than LEO SAR, leading to great changes of the information acquisition and recovery: the synthetic aperture time reaching several minutes or even tens of minutes, echo round-trip delay reaching up to the sub-second level, wide swath covering thousands of kilometers.

The influences of non-ideal factors, such as ionosphere, will be time-space varying accordingly as the integration time and the swath increase. Due to the huge variance of the slant range history in time-space dimension, the classical SAR system design and signal processing methods have obvious errors or even fail. 

The scope of this speech is to generally state the GEO SAR concept, the key problems and the corresponding solutions, including system design and performance analysis, accurate imaging algorithms under curved trajectory and large wide swath, time-space varying ionospheric effects and compensation, the equivalent validation experiment based on Beidou navigation satellites. Finally, the representative achievements and research institutes in China are summarized, and the development trends of GEO SAR in future are prospected.
