摘要：
According to the electron density distribution simulation of electron-beam-generated air plasma based on Monte-Carlo model, we established a model of shape parameters and electromagnetic parameters of the plasma in different situations. Using the model, we calculated the electromagnetic scattering of radar targets in the presence or absence of electron-beam-generated air plasma covering. Besides, the average relative attenuations of the electromagnetic scattering in different cases were acquired. Then the simulation results were compared with experimental results in corresponding situations. The comparison indicates that the simulation results of the electron distribution based on Monte-Carlo model are reliable. Moreover, the presented model of shape parameters and electromagnetic parameters provide a new approach to investigate the characteristics of electron-beam-generated air plasma in detail.
