Recently, North Korea''s ballistic missile threat is greater than ever, and this is putting a lot of pressure on Korea Air-Missile Defense(KAMD). To overcome this situation, we are trying to establish a multi-layered missile defense system by developing a long-range weapon system such as L-SAM, but considering the decrease in military service resources due to South Korea''s low birth rate, military quantitative expansion can reach a limit in terms of supplying and operating equipment. Therefore, research is needed on ways to improve the defense effect by making the most of existing defense assets.
To this end, this paper presents a plan to apply cooperative engagement to the existing missile defense system, using CEC(Cooperative Engagement Capability) and IFC(Integrated Fire Control) as examples. First, a ballistic missile trajectory simulator was implemented, and problem environments are created by considering the various types of ballistic missiles in operation by North Korea. Next, among the IFC types, the Precision Que and Forward Pass are applied on defense system by exploring the types applicable to the current operating system. Finally, it is confirmed that the defense effect of various ballistic trajectory types when performing cooperative engagement in the implemented system is superior to that of the conventional engagement.
Based on these results, radar and radar resources, which are not previously covered, are considered in a dynamic environment to formulate the Weapon Target Assignment(WTA) problem considering cooperative engagement. Considering the characteristics of the environment, it is confirmed that the method of converting the dynamic problem into a static problem by classifying the decision variable into an independent and dependent relationship had the best performance. For faster calculations and better performance, we propose two methods :one is performing a battery-target assignment using GA(Genetic Algorithm), and then using heuristic algorithms to convert battery-target to interceptor-target assignment, and the other is all processes with heuristic algorithms.
