Circular-scanning Synthetic Aperture Radar (SAR) can quickly generate vast maps of earth's surface, providing precise positioning information by scene-matching approach. Although it has gained more attention to improve the imaging method, the quantitative comparison of the theory performance, between circular-scanning SAR and other classical imaging SAR mode, is obliviously performed in previous work...
The centerline is an important feature in ISAR image features. In this paper, a new ship centerline extraction algorithm is presented. In the improved algorithm, the width character is used in the extraction of the ship centerline, and the line detection in normal centerline detection methods is replaced by line group detection. After finding the ship width and angle, the centerline position can be...
