Microlocal aspects of bistatic synthetic aperture radar imaging [PDF]

arXiv, 2010
In this article, we analyze the microlocal properties of the linearized forward scattering operator $F$ and the reconstruction operator $F^{*}F$ appearing in bistatic synthetic aperture radar imaging. In our model, the radar source and detector travel along a line a fixed distance apart.

Indoor Synthetic Aperture Radar Measurements of Point-Like Targets Using a Wheeled Mobile Robot [PDF]

arXiv
Small, low-cost radar sensors offer a lighting independent sensing capability for indoor mobile robots that is useful for localization and mapping. Synthetic aperture radar (SAR) offers an attractive way to increase the angular resolution of small radar sensors for use on mobile robots to generate high-resolution maps of the indoor environment.
