In the modem complex electronic systems, built-in test （BIT） technology, used as important means to improve system maintainability and testability, is popularly valued and widely applied increasingly. On basis of design principles, BIT system uses a multi-computer distributed architecture, fault detection circuit and fault detection software adopt generalized design, and fault location is based on fault propagation diagraph. The maintainability of radar equipment and condition monitoring are probed, and the implementing architecture of built-in test system and fault locating principle based on fault tree algorithm are mainly depicted, the operating principle of generalized fault detection circuit is introduced, and the issues noted in design and its corresponding solutions are summarized.
