THE ANALYSIS OF RANGE-ALIGNMENT IN INVERSE SYNTHETIC APERTURE RADAR IMAGING
逆合成孔径雷达成象中距离校正的研究

In this paper, the basic theory of range-alignment in Inverse Synthetic Aperture Radar (ISAR) imaging is analysed. Two new methods of range-alignment are proposed. One is peak point alignment, and another is direct range-alignment. Based on the measurel radar data, the differences between the above-mentioned new methods and amplitude correlation method are liscussed, resulting in the confirmation on the superiority of the direct range-alignment method.
