一种多目标ISAR成像方法
A Method of Multi-target ISAR Imaging
摘要
Abstract
ln multi-target inveme synthetic aperture radar( ISAR) imaging, when the targets are very cloae and the reWive radial velocity is large, we can not resolve it using existinS multi-target imaging methoda. In order to solve this problem, the use of the Radon transform and a modified envelope correlation method for multi-target ISAR imaging is presented. The radon transform is used to align the range profdes coarsely. For more accuracy alignment, a modified envelope correlation method combining with target separation technique and cune fitting technique is proposed. After range alignment, phase compensation is fulfilled by discrete chirp-Fourier trarnsform ( DCFT). The simulation results show that the method proposed in this paper is effeaive.关键词
