In the developing process of tactical software in aerial defence ground equipment,the tactical software was devel⁃oped gradually, because of running short of integrity requirement. The system software is designed in reason, so that exten⁃ding the software design cycle,and increased thedifficulty of the software design. Design of the system software, can shorten design cycle and reduce thesoftware software design difficulty. In this paper, an analyzing method of tactical software in aerial defence ground equipment is presented, in base of anciently designing of system software. The analyzing method including system environment analysis, system task processing level, logic network, the original form of logical network merging and layer by layer analysis produced results. The analyzing method bring help to the tactical system software design in the future, including how to start analysis system, those contents of the software system to carry on the analysis and how to analyze the work,before document preparation.%在地空导弹武器系统软件的研制过程中,随着型号研制要求的不断变化,战术软件的研制需求往往不能一步到位,导致软件在研制过程中,需要不断进行完善,延长了软件设计周期、增加了软件设计的难度。对软件进行系统化的设计,可以缩短软件设计周期和降低软件设计难度。在总结以往系统软件设计的基础上,给出了一种地空导弹武器系统战术软件系统设计的分析方法,包括系统环境分析、系统任务处理层次、逻辑网的原始形成、逻辑网的归并和逐层分析生成结果。该方法能为战术软件系统设计人员在将来的系统软件设计中,如何入手分析系统,在文档编写之前,对系统软件的那些内容进行分析,如何分析等工作的开展带来帮助。
