摘要

The pulse repetition frequency (PRF) variation of SweepSAR mode has significant impacts on image quality. The influence of SweepSAR mode PRF variation on azimuth signal is analyzed, and the mathematical modeling of SweepSAR PRF variation is implemented. Besides, based on the analysis and paired echoes theory, the formulas of the amplitude and position of azimuth paired echoes are derived. The relationship between PRF variation and the amplitude and position of paired echoes is quantitatively described. Finally, the computer simulation verifies the validity of theoretical analysis.
