This paper discusses the use of selected artificial intelligence (AI) techniques for integrating multisource information in order to develop an understanding of an ongoing situation. The approach takes an active, ``top-down'' view of the task, projecting a situation description forward in time, determining gaps in the current model, and tasking sensors to acquire data to fill the gaps. Information derived from tasked sensors and other sources is combined using new, non-Bayesian inference techniques. This active approach seems critical to solve the problems posed by the low emission signatures anticipated for near-future threats. Simulation experiments lead to the conclusion that the utility of ESM system operation in future conflicts will depend on how effectively onboard sensing resources are managed by the system. The view of AI that will underly the discussion is that of a technology attempting to extend automation capabilities from the current ``replace the human's hands'' approach to that of replacing or augmenting the human's cognitive and perceptual capabilities. Technology transfer issues discussed in the presentation are the primary motivation for highlighting this view. The paper will conclude with a discussion of unresolved problems associated with the introduction of AI technology into real world military systems.
