逆合成孔径雷达成象中距离校正的研究
THE ANALYSIS OF RANGE-ALIGNMENT IN INVERSE SYNTHETIC APERTURE RADAR IMAGING
-
摘要: 本文分析了逆合成孔径雷达(ISAR)成象中距离校正的基本原理,提出了两种新的校正方法:峰值对准法和直接校正法。利用雷达实测数据,讨论了上述新方法与幅度相关法的差别,从而肯定了直接校正法的优越性。

Abstract: 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. -
