Integrating Physical and Informational Sensing to Support Nonproliferation Assessments of Nuclear-Related Facilities

Nonproliferation assessments necessarily rely on multi-source information such as physical sensor measurements, sampling results, overhead imagery, and open source information that can provide secondary or supporting indicators of facility operations. These data streams are traditionally assessed by disparate analysts who have subject matter expertise in the specific data streams. However, and integrated approach in which multisource, multimodal data (e.g. quantitative data and ground-based images) is assessed in a single platform, and in which data sources can inform or even queue one another, provides an opportunity for a more comprehensive analysis. In this paper, we will describe efforts to first understand new or emerging unimodal and multimodal sensing mechanisms, and then detail our research into how these data steams can be integrated for a holistic nonproliferation analysis.
