Prognostic Health Management of an RF System Using GPS

Prognostic health management (PHM) of electronic systems presents challenges that traditionally were not worth the cost of pursuit. Recent changes in weapons platform acquisition and support requirements have spurred renewed interest in electronics PHM, revealing accessible data sources and previously unexplored predictive techniques. This article discusses the development and validation of electronic prognostics for a radio frequency (RF) system. The solution has applicability to a broad class of mixed digital/analog circuitry, including radar and software-defined radio.
