Chinay analyzing the time evolution of artificial plasma cloud in the high altitude of atmospheric environment;
we found that there are two zones;
an exponential attenuation zone and a linearly attenuating zone;
existing in the spatial distribution of electron density of the artificial plasma clouds. The plasma generator's particle flux density only contributes to the exponential attenuation zone;
and has no effect on the linear attenuation zone. The average electron density in the linear attenuation zone is about 10-5 of neutral particle density;
and can diffuse over a wider area. The conclusion will supply some valuable references to the research of electromagnetic wave and artificial plasma interaction;
the plasma invisibleness research of missile and special aerocraft;
and the design of artificial plasma source.;
