Abstract

When a synthetic aperture radar, employing an ultra-wideband impulse waveform, forms an image of an area on the ground by using a backprojection algorithm, artifacts occur due to any strong reflectors in the scene. These artifacts can obscure or influence the image of the area containing low-level reflectors that may be of interest. Herein, we examine the factors of the imaging geometry that leads to these artifacts or influences and propose a procedure for reducing them. We demonstrate the artifacts and the procedure to reduce them with the data collected by the ultra wideband radar of the U.S. Army Research Laboratory.
