FTA-based assessment methodology for adaptability of system under electromagnetic environment

In order to develop a methodology for assessing the adaptability of system under electromagnetic environment especially RF environment, a Fault-Tree-Analysis-based method is proposed considering the possible performance degradation, disfunction and fault. A component-level and a system-level assessment are performed. An approach to describing logical and hypotactic relation of nodes in Fault-Tree Analysis is designed and illustrated in detail. A software platform is developed to implement the system-level assessment.
