DSS-SAR-GMTI APPLIED IN THE UNEVEN BACKGROUND

摘要：

The baseline in distributed small satellites SAR (DSS-SAR) system can be decomposed into the across-track component and the along-track component. For GMTI by interferometry, the Across-track Interferometry (XTI) phase can influence the Along-track lntefferometry (ATI) phase. Instead of converting the along-track baseline into interferometric interval in the processing, starting with the echo datum basing on the mixed baselines existing at the same time, the impacts of the across-track and along-track baselines on the phases of moving and stationary targets are analyzed respectively, and the echo datum obtained from different satellites at the same time are imaged. The slide windows detection method is proposed to compensate the phase of the stationary targets in the interferograms after co-registration. Simulation, carried out on uneven terrains with different altitude, validates the method.
