Smart built-in-test (BIT): an overview

The author reviews the smart BIT (built-in-test) efforts that Grumman has conducted for RADC (Rome Air Development Center). Their goal has been the elimination of false alarms by adding AI (artificial intelligence) to BIT to accomplish smart BIT. RADC has sponsored several efforts under the smart BIT heading whose emphases have been to improve the ability of BIT to make more robust decisions based on knowledge of the situation rather than using a simple GO/NO trigger mechanism. This knowledge comes from various sources, including internal functions, external environment factors, and temporal monitoring. This knowledge has been captured and used by means of various AI and related techniques. Particular attention is given to the implementation of temporal monitoring software and to the smart BIT for Joint Surveillance Target Attack Radar System (Joint STARS)
