Abstract
Shadow imaging is a technique to obtain highly resolved silhouettes of resident space objects (RSOs) which would otherwise be unattainable using conventional terrestrial based imaging approaches. This is done by post processing the measured irradiance pattern (shadow) cast onto the Earth as the RSO occults a star. The research presented here focuses on recent developments in shadow imaging of geosynchronous (GEO) satellites with near stationary orbits approximately 36,000 km from the Earth. The fundamental resolution limits of shadow imaging are quantified analytically as a function of spectral bin width of the collected light. A set of simulated imagery is shown to agree with analytically derived resolution limits.
