Abstract
Image rotation plays an important role in image understanding. The rotation of inverse synthetic aperture radar images can be done either in the image forming process or after. Also, when the image is rotated in the imaging forming process, it can be performed both in the time-domain and the frequency-domain. This paper introduces three methods for the rotation of ISAR images. Experimental results are presented to demonstrate the effectiveness of these methods.
