| 摘 要： | 针对InlSAR三维成像中的图像配准问题进行研究,从理论上推导了同一基线上两干涉天线之间图像失配准的原因,并定量分析了图像失配准量对后续干涉处理的影响.研究表明,初始时刻同一基线上两干涉天线间的波程差引起两幅ISAR图像距离方向的亚像素级失配,而成像积累时间内两干涉天线波程差的变化量则引起两幅ISAR图像多普勒方向的像...

| Abstract: | Aimed at the image registration problem in interferometric inverse synthetic aperture radar(InISAR),the causation of the offset between two ISAR images for different interferometric antennas along one baseline was analyzed.Then a quantitative analysis of the offset and its influence on the following interferometric processing was discussed.It was shown that the sub-pixel offset in the down-range direction and the pixel offset in the Doppler(cross-range) direction induced mismatching of two ISAR images.A nov... |
