| Abstract: | BIT technology is an important way to improve the testability and maintainability of system or equipment. Basic principles of missile-borne computer BIT design is proposed which provides a typical method based on feature research of missile-borne computer BIT technology. The practice proves that the design method is applicable to many types of missile-borne computer, and fault detection rate is more than 90%, and then false alarm rate is less than 2%, which significantly improves the reliability, testability and maintainability of missile-borne computer. |
