Abstract

This paper addresses the problem of imaging a dynamic object with an imaging modality that utilizes a single illumination instead of sequential sector scanning used in conjunction with B-scanners. Two data collection strategies and their associated reconstruction algorithms are presented for dynamic object imaging. One scheme utilizes a single unfocused wave transmitted by an element of an array. In the other method, the elements of an array simultaneously illuminate the object with unfocused multiplexed waves. The data base acquired in either of these methods is sufficient for the recovery of the object's monostatic synthetic aperture data and reconstruction.
