Mathematical and numerical modeling of moving inhomogeneous weakly ionized gas-plasma flows for determination of target scattered fields

The electrodynamic models of scattered fields of moving inhomogeneous weakly ionized plasma media are based on the study of its gas dynamic and plasma physical properties. The solution of different radio physical (radar) problems requires the determination of the electron density distribution over jet volume. Such distributions have been obtained by the help of presented in this paper full and simplified analytical and numerical models of gas dynamical jet in air wake. It has been detected that these distributions are not connected with the gas density distribution and are determined by the temperature distribution. The developed model allows simulating the jet behaviour with high enough accuracy. The calculations of spatial electron density distribution in the wide range of flight velocities and power plant parameters and for different regimes of jet effluxes in ambient space were performed.
