Abstract :
The authors report on the development of an approach for performing fault detection and isolation in RF subsystems using a highly integrated system-level operation. By integrating diagnostics into system-level operation RF subsystem faults are detected and isolated to the line replaceable module (LRM). This study is conducted in the context of the communication navigation identification (CNI) subsystem and the electronic warfare (EW) subsystem developed by TRW avionics
