ANALYSIS OF RANGE ALIGNMENT IN INVERSE SYNTHETIC APERTURE RADAR IMAGING

摘要

In this paper,the basic theory of range alignment in Inverse Synthetic ApertureRadar(ISAR)imaging is analyzed.Two new methods of range alignment are proposed:one ispeak point alignment;another is direct range-alignment.Based on the measured radar data,thedifferences between the above-mentioned new methods and the amplitude correlation method arediscussed,resulting in the confirmation on the superiority of the direct range-alignment method.
