Abstract:
Ground-based short-wave infrared (SWIR) imaging is a low-cost and informative method of daytime Geosynchronous (GEO) satellite detection and characterization. However, for large solar phase angles, spectral sky brightness and low satellite reflected signal combine to make this approach more challenging. A generalized model for satellite spectra using diffuse reflection was developed and compared to modeled atmospherics to determine the most promising bands-of-interest. This research will show that SWIR-band imaging offers distinct advantages over the visible for daytime GEO satellite custody and investigate the utility of SWIR band imaging particularly near twilight.
