Abstract: Pointing at the complexity of time unified and terminal system’s hardware architecture of the shooting range, this paper improves the original solution of the design technique of IRIG-B decodulation and system control, in terms of project implementation. Under the premise of observing GJB, it simplifies the hardware structure and innovates in design of system. It realizes the practice of integrated design time unified and terminal system based on FPGA’s Nios Ⅱembedded processor, and finishes decoding IRIG-B code(DC and AC).
