Abstract :
ISAR imagery measures range and radial velocity of scatterers from targets of interest. Due to wave action, a ship has constantly changing roll, yaw and pitch angular velocities, which makes the ISAR images quite changeable from frame to frame. A method is described for extracting 3D model information from a sequence of two dimensional ISAR images, with no knowledge of the ship motion, but with the assumption that the scatterers can be correctly labelled from frame to frame. A later paper will describe a labelling method for use with real images which justifies this assumption.
