Study on Key technology of BIT and self diagnosis of complex weapon equip

It is an important approach that BIT(built-in test)can be used to improve the diagnosis ability of weapon system along with the weapon equip complexity increasing. And it is put forward that self diagnosis technology based on BIT is significant by analyzing the internal property of BIT and combining the correlative studies. Then detailedly analyzes the principle of self diagnosis system based on BIT and the approach of technology study. And its key technology is discussed on how to construct a self diagnosis system based on BIT. Finally it is viewed that the foreground of the application of self diagnosis system based on BIT.
