Comparison of filtering algorithms for ground target tracking using space-based GMTI radar

Space-based radar (SBR) systems have received a great deal of attention, since they can provide all-weather, day-night, and continuous world-wide surveillance and tracking of ground, air, and sea-surface targets. The ground moving target indicator (GMTI) mode is an important operating mode for such systems. GMTI radar measurements are the range, azimuth and range-rate, which are nonlinear functions of the target state. We consider the extended …
