“…If any performance of C21–C25 and C26–C28 is damaged, it can lead to the failure of the system-level defensive task, including the space-segment and ground-segment defense. Therefore, if the eight basic performance indices satisfy the serial-parallel integrated relation, the WPM can be used to calculate the comprehensive capability [ 28 ]. Thus, the space-segment comprehensive defensive capability P S,inv of the system and its ground-segment comprehensive defensive capability P G,inv are evaluated by using Eq.…”
