Disclosed are systems and methods for prognostic health management (PHM) of electronic systems. Such systems and methods present challenges traditionally viewed as either insurmountable or otherwise not worth the cost of pursuit. The systems and methods are directed to the health monitoring and failure prediction of electronic systems, including the diagnostic methods employed to assess current health state and prognostic methods for the prediction of electronic system failures and remaining useful life. The disclosed methodologies include three techniques: (1) use of existing electronic systems data (circuit as a sensor); (2) use of available external measurements as condition indicators and degradation assessor; and (3) performance assessment metrics derived from available external measurements.

Systems and methods for predicting failure of electronic systems and assessing level of degradation and remaining useful life

A method and apparatus are present for monitoring a platform. Information from monitoring the platform is received from a sensor network and a number of systems associated with the platform. A plurality of observations is formed from the information. A profile is created from the plurality of observations in which the profile is used to monitor the platform.

Failure Mechanisms of Radar and RF Systems

A method and apparatus for determining a health of the system. Groups of vibration data are identified for the system. A group of vibration data in the groups of vibration data comprises data for vibrations of the system at different frequencies over time. The groups of vibration data for the system are stored in a number of associative memories in a computer system. The health of the system is identified based on the groups of vibration data in the number of associative memories. The groups of vibration data include images of the vibrations of the system.

According to an aspect of the invention, a method for monitoring the state of health of an electronic data carrier is conceived, wherein a reader device operable to read data from said electronic data carrier determines the state of health of the electronic data carrier by reading a parameter value indicative of said state of health from the electronic data carrier. According to a further aspect of the invention, a system for monitoring the state of health of an electronic data carrier is provided, the system comprising a reader device operable to read data from said electronic data carrier, wherein said reader device is arranged to determine the state of health of the electronic data carrier by reading a parameter value indicative of said state of health from the electronic data carrier.

The maintainability and reliability of critical electronic systems such as radars and global positioning system (GPS) on military and commercial aircrafts is a significant concern. Practical condition assessment and prediction of remaining useful life for such systems offer significant potential for improved readiness and field reliability. This paper introduces the 'circuit as a sensor' concept as an innovative and practical PHM solution for electronic systems through proof of concept using radio frequency digital (RF/D) systems. To demonstrate the feasibility of this concept, an economical test platform operating in the frequency range representative of modern avionic systems, with available system and component features was selected. An experiment to study the effects of degradation from the highly accelerated tests on diagnostic features as well as derive failure progression trends was conducted. Results from this research are presented. The embedded diagnostic and prognostic capability developed is scalable and can be applied to broad class of electronic systems.
