RESEARCH ON 3-D IMAGING TECHNIQUE FOR INTERFEROMETRIC INVERSE SYNTHETIC APERTURE RADAR

该文提出了干涉式逆合成孔径雷达三维成像的方法,并对于涉式测角出现的角闪烁现象提出了判断并剔除角闪烁点的准则。然后分析了两种跟踪体制下的三维成像方法,并提出了克服连续跟踪体制下跟踪误差引起的相位随机抖动问题的方法,解决了步进跟踪体制下各天线ISAR像焦点对齐问题。

In this paper, a 3-D imaging technique for interferometric inverse synthetic aperture radar is presented. And the criteria of determing and the angle glint in interferometric angle measurement are given. Furthermore, the 3-D imaging technique under two tracking systems is analyzed. This technique can effectively overcome the random phase dithering caused by tracking error under the continuous tracking system and satisfactorily solve the alignment of the different focuses of ISAR images under the step tracking system.
