This thesis documents the design and implementation of a radar imaging system. A rail system was constructed to control the location of an off-the-shelf ultra-wideband (UWB) radar along a linear path. Range imaging, cross-range imaging, and synthetic aperture radar (SAR) imaging algorithms were implemented in Matlab based on the data from the radar. Results are presented for a variety of target scenes. The radar imaging system can be used for future research of radar imaging algorithms as well as for classroom demonstration for a radar course at Baylor University.
