Abstract

Abstract:

In millimeter wave high resolution SAR imaging, the existing squint SAR cross-track motion compensation algorithm brings into a phase error of more than π/4 during the imaging process. The phase error would worsen the compensation effect. This paper transforms the squint slant range with the motion error into the side-looking slant range. We adopt the side-looking cross-track motion compensation algorithm to cross-track motion compensation. The proposed algorithm works well on the millimeter wave real data in the 10° squint angle and the results are better than those obtained by existing algorithms in the same squint angle.

Key words: synthetic aperture radar(SAR), high resolution, squint, millimeter wave, motion compensation
