Bistatic inverse synthetic aperture radar (BiISAR) imaging and interferometric inverse synthetic aperture radar (InISAR) imaging can provide complementary information to monostatic inverse synthetic aperture radar (MoISAR) imaging. Time synchronization is a requirement for both systems. This paper focuses on the problem of the time synchronization in the BiISAR and InISAR imaging with a polynomial time synchronization error model (PTSEM) in theory. The effects of the time synchronization errors to the range and azimuth compression with the synchronization errors are analyzed in detail. A phase error model transferred from the synchronization errors to the interferometric error is established. A simulation displays the results of the analysis.
