As modern weapon systems become more and more complicated, the BIT(Built in Test) technology has increasingly become an important means to enhance the maintainability and testability of the intricate electronic system. In this paper, the method of radar data acquisition and feature extraction system's DFT(design for testability) is studied, and an architecture of BIT based on DSP +dual FPGA is proposed. The design is proved eligible by fault emulation.
