Abstract :
Three methods of ISAR image reconstruction are presented. The first is the line-of-sight image reconstruction based on the narrow angle approximation. The second is the fixed scene image reconstruction via proposed polar-to-rectangular coordinate transformation which is based on the nearest neighbor interpolation utilizing the Delaunay triangulation. The third method is to obtain images directly from the polar format data without the coordinate transformation
