Under the conditions of informatization, the electromagnetic environment of the battlefield is becoming increasingly complex, sothe electromagnetic compatibility(EMC) problem faced by airborne weaponsis very prominent. Based on the analysis of the EMC standards of domestic and foreign weapons, and the design thinking of system of systems(SoS), this paper proposes a method for establishing the EMC standard SoS for airborne weapons, and uses this method to initially construct an EMC standard SoS for airborne weapons, which can be used to provide technical support for the SoS-level, system-level,and component-level EMC tests for the airborne weapons.
