Knowledge Intensive Interpretation Of Signal Data
IEA/AIE'2004: Proceedings of the 17th international conference on Innovations in applied artificial intelligence（2004）
摘要
This paper discusses the use of knowledge for the interpretation of signal data in a laboratory prototype system known as ELEXSA (ELINT Exploitation for Situation Awareness). ELEXSA uses knowledge intensive techniques to yield information products that aim to assist a military commander to comprehend the significance of detected entities, their relationships with own force platforms, and the effects of those relationships relative to the commander's goals. The core interpretation components of ELEXSA are structured in the manner of the lambdaJDL information fusion model. These components make intensive use of corporate knowledge bases detailing the capabilities of military systems, models of operational concepts and of the physics of propagation of radar signals. An illustration is provided which shows how an ELEXSA information product is constructed. Technical issues are identified and future directions of this work are also presented.
