英文摘要： Against the limitation on engineering application of electromagnetic pulse effects simulation, the linear energy coupling model is established by electromagnetic pulse effects experiment by standard, it can predict the response of the Equipment Under Test (EUT) under any electromagnetic pulse through the model. This method can be a supplement of the mechanism modeling method. A method is put forward to establish the energy coupling model between electromagnetic pulse and electronic equipment by using system identification theory,which includes the electromagnetic pulse effect experiment design, test data denoising method, identification algorithm and the tested equipment input signal sensitive parameters,etc. The project combines experimental and theoretical research.The modeling is based on experimental test and the parameters of model are extracted from test data by using of system identification theory. The experimental research provides the data for theoretical study, and verifies the validity of the modeling theory. Related research achievements have won a second class prize of 2009 National Science and Technology Progress. One project of Key Lab of Defense Science & Technology Foundation and one project of National Natural Science Foundation scientific instruments special (10927506) were approved based on the research achievements. There are 18 articles are published and 7 of them are indexed by EI. One book is published.Five graduate students have been trained through the project. The research results provide a new simulation method for weapons equipment electromagnetic pulse effect evaluation.
