Abstract

This paper discusses the methods for ground moving target identification (GMTI) in a bistatic ultra-wideband and wide- beam (UWB-WB) SAR system. Simulations of GMTI in UWB-WB SAR system are shown. Bistatic compensation in a time domain SAR processing system is given, and clutter leakage caused by bistatic radar and time domain fast backprojection SAR algorithms is studied. The clutter leakage is investigated both for the scatter and for the sidelobes of the scatter. In the paper we also discuss clutter leakage caused by bistatic scattering. As the scatter size increases the bistatic wave will scatter differently then the monostatic wave. Also the effect of bistatic nadir and antenna configuration is studied.
