This paper presents results of the investigation of the CLEAN technique used for the generation of 3D images from sparse frequency space data taken on curved SAR aperture paths. Preliminary images resulting from a helicoptor bourne spotlight mode SAR is encouraging. An efficient visualization technique allows improved interpretation of CLEAN images to a degree that a focusing error can be identified. A correlation technique able to accomodate edge effects and possibilities for larger 3D CLEAN images are presented.
