This initial phase of the effort is focused on developing and understanding appropriate definitions, tools, and methods applicable to the problem of providing reliable information in highly dynamic physical and communication environments. A fundamental criterion of the defining phase is to apply compatibly efficient methods and to investigate relationships within the available information space that are hierarchical in their segmentation, assignment and processing of information. This process establishes a foundation for the objectivication of the underlying properties in the information space that is consistent with the capabilities provided by the methods and tools used to extract, enhance, or verify the information. Ultimately, this should lead to an information alphabet that allows rapid identification objects within the information environment. As applied to this project, the alphabet and the associated syntax for building objects, will be used to define, and hence reduce, the impacts and effects created by noise in the information gathering, and transmission processes. This formulation of the information environment will also be applicable to other object related activities, such as, compression, identification, tracking, and enhancement, and thus, will provide a computationally efficient foundation for various information processing activities in highly dynamic environments, such as those anticipated for UCAV or hypersonic missile systems.
