摘要

Under the consideration of non-steady case,a set of equations is derived,which describes the non-steady nonlinear interactions between plasma and field in the far wake region of a space vehicle.Numerical calculations are also made and the numerical results show that density cavities and electromagnetic solitary waves are generated due to the modulation instability,if the envelope of high frequency modulation field is strong enough.This is of great significance to the detection of disguised space vehicles.
