                         (FFBP) algorithm that is based on an extension of the quadtree 
                         approach. A flexible 3D tree structure is generated from a 
                         modified Morton order or Z-order curve, a recursive space-filling 
                         curve that is suitable for FFBP algorithms. This paper presents, 
                         as well, an original method for defining sub-apertures. The 
                         proposed algorithm can be applied to any flight path and is about 
                         90 % faster than the direct backprojection, yielding 
                         high-resolution 3D images with low phase errors and high degrees 
                         of coherence.",
