摘要：
To suppress the high grating-lobe caused by phase discontinuity of frequency bandwidth synthetic, a new approach of frequency synthetic bandwidth is proposed in this paper. First, sub-pulse is compressed and frequency bandwidth is synthesized. After frequency bandwidth synthesized, second range compression and the range migration correction is implemented. Then, the effect of phase discontinuity on frequency synthetic bandwidth is avoided due to the corrected range migration correction. Finally, Chirp Scaling is applied to obtain the squinted two-dimension high resolution SAR image.
