Our research centers on techniques for passive optical remote sensing and imaging of manmade objects in geosynchronous Earth orbit (GEO). Resolved imaging of GEO satellites continues to be a challenging problem due to their great distance from both ground-based locations and low Earth orbit (LEO). We are currently interested in both (1) data processing techniques and optical designs to maximize the imaging performance of spaceborne cameras, and (2) more exotic synthetic aperture techniques, such as shadow imaging based on measurements of the Fresnel diffraction pattern of the object silhouette during stellar occultation. Results from analysis and simulation of synthetic aperture techniques will guide future imaging architectures and experiments aimed at improved characterization of space objects.
