Abstract
A system for localization includes a radar, a database, a simulator, a registrar, and a filter. The radar is positioned at a disposed location requiring localization. The radar generates a radar image scanning a proximity around the disposed location. The database stores features of a landmass. The simulator generates synthesized images of the features that the radar is predicted to generate from corresponding viewpoints. The registrar calculates respective correlation indicators between the radar image and each synthesized image. The filter sets a pose estimate of the disposed location to an average of those viewpoints from which correspond the synthesized images having the best or better ones of the correlation indicators.
