At present, high intensity radiated field (HIRF} cannot be simulated under the condition of laboratory, and it is hard to carry out the electromagnetic radiated susceptibility and safety margin test for system. In order to solve the problems above, we researched the theory, method and implementation technique of substuting injection for radiation. In line with the principle of limited target, in allusion to typical interconnected system, the equal response voltage on the equipment cable port was regarded as the equivalent principle. The equivalent substitute model and injection source extrapolation model in HIRF condition were established. The terminal response voltage calculation method was presented based on the Baum-Liu-Tesche(BLT) equation and the transmission line theory. Two conditions of substuting injection for radiation were determined. One was the same equivalent source, and the other was the same output impedance. The equivalent correspondent relation between injection voltage and radiated field was put forward theoretically. Injection coupling module was adopted as support equipment for the equivalent substitute test. The forward voltage extraction, interference signal injection and normal transmission signal monitoring in interconnecteds system were achieved. A new electromagnetic environment effect test method combining injection with radiation for interconnected systems was proposed, providing practical research methods and technique supports to correctly evaluate the electromagnetic susceptibility and safety margin of interconnection system.
