The range test is a necessary step in the system development process of an air defense weapon system.Due to the development of collaborative operations,the air defense weapon system has complex composition and nu-merous data sources.In this paper,a piece of combat demonstration software is designed and implemented based on the Qt platform in order to improve the combat demonstration effect of the air defense weapon system.The software presents the system combat capabilities and real-time status of equipment in multiple ways.In addition,it provides users with a friendly air situation display interface.The design and implementation of the software are described from three aspects,namely overall design,business logic,and human-computer interaction in this paper.
