摘要
Abstract
Applying the case signal model, a preliminary understanding of electromagnetic pulse(EMP) generated by detona-tions in space has been developed in this paper. Taking into account of the relativistic effects, recalculation of the formation time of the space charge limit was accomplished which suggested that once the space charge was formed, the system could be treated as in the quasi-steady situation. Based on that point, frequency of the space charge oscillations has been analytically derived and semi-numerically calculated. The results agree with each other very well. For observers in large distances, a net dipole moment can be resulted from the average movements of space charges. Calculations indicate that the peak value of the radiation signal in the far field always appears before the maximum time of nuclear reactions and is close to the formation time of the space charge limit.关键词
