SUPPLEMENTING HIGH-RESOLUTION SATELLITE IMAGERY WITH LOWER RESOLUTION MULTISPECTRAL AND RADAR IMAGERY FOR SAFEGUARDS APPLICATIONS

摘要

The most frequent use of satellite imageries for nuclear safeguards is the visual interpretation of highresolution optical satellite imagery. However, these images are not always available either because a specific site was not tasked or archived in the past, or the area has been obstructed by cloud. This paper shows how low-resolution multispectral (LANDSAT) and radar imagery (RADARSAT-1) can be used to supplement and complement high-resolution optical imagery in the remote verification of nuclear related facilities with two case studies.
