Abstract
As battlefield fluidity increase, the need for current and accurate situation awareness increases. Critical to providing this awareness will be recce input. This input will need to be both timely and specific, that is, input will need to provide timely updates of only information which is critical. The use of multiple high speed sensors by recce aircraft will result in increases in data and knowledge changes. Many of these changes will be non- critical and could be contributors to information overload if constantly updated. There is a need to determine the significance of the changes and when they effect the battlefield environment enough to require updating/coordinating of situation awareness databases. This implies a need for recce aircraft to: (1) determine when there is a change, (2) determine the effect and criticality of the change(s), and (3) provide (only) necessary updates. This paper presents a discussion of ways to accomplish these needs and some current activities that are addressing the problem of determining when (and what) changes have occurred. The discussed method uses existing imagery and database information that can be cross correlated with new sensor inputs to determine changes in: (1) number and position of objects, (2) speed and handling of objects, and (3) whether the changes are significant enough to require immediate update of situation awareness.
