摘要

When the sliding spot light SAR works in high squint mode, there will be distortion in the two dimensional spectrum of the signal due to the coupling in range and azimuth. What's more, the extension of azimuthal spectrum will cause spectrum overlapping. Traditional deramp algorithm can't completely solve this problem. By using a modified azimuthal pre-process to eliminate the alias, this paper proposes a novel NCS algorithm for Squint Sliding Spotlight Mode SAR. Simulation results show the validity of this algorithm.
