Abstract:

Space Situational Awareness has become a key issue both for defence and civilian/industrial applications.  Identification of potential or active threats and monitoring of key assets and operations are at stake. This activity also includes the follow up of dedicated satellites (such as telecommunication, observation), traffic handling, debris identification and tracking. We present current work performed at Onera on Adaptive Optics (AO) for Low Earth Orbit (LEO) satellite imaging. We describe briefly our AO system and its performance. We also address recent developments on image post-processing based on marginalized blind deconvolution combined to parsimonious PSF modelling.  Finally, we present on sky results.
