In recent conflicts, such as those in Ukraine and the Middle East, the critical importance of advanced combined air-defense missile systems for combat effectiveness has become increasingly apparent. These integrated systems are tasked not only to detect and engage a spectrum of enemy threats but also to adapt swiftly and reliably to dynamic, rapidly changing circumstances, especially after missile launch. To verify advanced combined air-defense missile system's functionality after missile launch, it is ideal to conduct comprehensive system tests using various scenarios and actual flight tests. However, due to limitations such as high cost and lengthy setup time, this approach is often difficult to implement in reality. In the past, system verification after missile launch has mainly relied on component-level inspections and HILS tests. While these methods can partially check individual system functions, they are not sufficient to fully verify all system functions as a whole. This paper proposes a system integration test method that uses a system integration simulator capable of simulating various combat scenarios and a missile beacon equipped with a missile flight model. Missile flight model uses the same algorithm as the guidance control method employed in actual missiles. Through the adoption of the proposed system integration test method, it was confirmed that a majority of previously limited and difficult-to-verify missile engagement-related test items can now be comprehensively validated. Furthermore, this method allows for comprehensive verification of the system's performance after missile launch, including its interoperability and response capability from a systemic perspective. It also contributes to increasing the reliability of the combined air-defense missile systems.
