According to the demand for analysis and assessment of burst control algorithm and fuze-warhead performance during design of GIF fuze, a digital simulation software of GIF fuze fuze-warhead system was developed. This software consists of parameter input module, main program module, data interface module, fuze-warhead matching performance analysis module and information storage module. The function and related key technologies of the modules were introduced. Visual and digital simulation of missile-target encounter and fuze war-head matching process of these targets can be conducted, cooperation efficiency of fuze and warhead of the burst control algorithm was eval-uated, and accuracy and efficiency of the burst control model were testified.
