Abstract:
The trapezoidal recursive convolution (TRC) finite-difference time-domain (FDTD) method is extended to study the bistatic scattering radar cross sections (RCS) of conductive targets covered with inhomogeneous, time-varying, magnetized plasma medium. The two-dimensional TRC-FDTD formulations for electromagnetic scattering of magnetized plasma are derived. Time-varying parabolic density profiles of plasma are assumed in this paper. The bistatic radar cross sections are calculated under different conditions using 2-D TE model for a conductive cylinder covered with magnetized plasma. The numerical results show that plasma cloaking system can successfully reduce the bistatic RCS, that the plasma stealth is effective, and that the appropriate parameters of plasma can enhance its effectiveness.
