Abstract

Composite electromagnetic scattering from a moving target above a ground is numerically simulated in this paper. This is useful for analyzing scattering properties in the field of target detection by GNSS reflected signals. Combining finite-difference time-domain (FDTD) method with a kind of equivalent form of relativistic boundary conditions based on scattering model, a moving target over a ground in a two dimensional electromagnetic model is developed. Scattering from an infinite perfectly conducting surface moving in a high speed is first computed by this method. And the results of the method are in good agreement with those of the method in the literature. The correctness and efficiency of this method is verified. Bistatic scattering from a moving target and a ground is obtained based on numerical distribution of the near fields. Finally the bistatic scattering coefficients of a two-dimension moving conducting object with various speeds above a plane ground are calculated.
