Detecting 3-D rotational motion and extracting target information from the principal component analysis of scatterer range histories

W Nel, D Stanton, MYA Gaffar - … for a Safer World"(RADAR 2009 …, 2009 - ieeexplore.ieee.org
ISAR imagery of ships are complicated by the 3-D motion of the target, which causes
blurring in the imagery. A technique is proposed which could help detect such motion and …
