The Prediction of Time Domain Electromagnetic Pulse Waveform Based on the Minimum Phase Method

摘要

With the rapid development of information technology and the wide application of electronic devices, the electromagnetic environment becomes more complex, external electromagnetic pulse may interfere with the electronic device at any time, affecting its normal work~1'-~2-~(31). Therefore, the electromagnetic pulse effect evaluation of electronic equipment is particularly important. In this paper, the complex electronic equipment system is like a "black box". It introduces the minimum phase method, regarding the electronic equipment systems to satisfy the condition of minimum phase signal transmission system'~(41). Its system impulse response can be obtained by measuring its input and output signals, and then to predict the electromagnetic pulse waveform of the equipment. In the experiment, the effect of the predicted waveform is verified ~(I5)'~(6)).
