摘要：

The electromagnetic (EM) scattering properties of a high-speed moving and time-varying plasma target are simulated in this work. The calculation model is first established for moving and time-varying dispersive medium with the Lorentz transformation and shift-operator finite-difference time-domain (SO-FDTD) method. Subsequently, the Lorentz-FDTD method is applied to calculate the EM scattering properties of the time-varying and moving plasma in a two-dimensional (2-D) case. Furthermore, the impact of the time-varying plasma parameters on the EM scattering properties is investigated. Finally, the bistatic radar cross section (RCS) of the time-varying plasma target is analyzed for various moving velocities and the results indicate that the EM wave is modulated by the time-varying and moving plasma, and the EM scattering of the time-varying and moving plasma is influenced by the moving velocity, time-varying properties, and plasma parameters.
