Ground Slow Moving Target’s Signal Analysis for Interferoemtric SAR

摘要：

Ground slow moving target detection using Interferoemtric SAR (InSAR) technique often omits the defocusing effect and just assumes that moving target has perfect Point Spread Function (PSF) as stationary point target does. In order to examine the defocusing effect on Interferometric Phase (IP) of moving target, we deduces the analytic description of moving target’s PSF and the interferoemtric phase under Along-Track Interferometric (ATI) mode and hybrid Along- and Across-Track interferometric mode. The effectiveness of moving target’s theoretical interferometric signal descriptions deduced is validated by simulations. Then, the clutter effects are also discussed and the interferoemtric signal modes of moving target plus clutter are also considered.
