Based on Maxwell's equations and the time-varying plasma constitutive equation, electromagnetic scattering characteristics by a sudden-created plasma slab can be analyzed. According to one-dimensional numerical analysis, a modified NPML(M-NPML) absorbing boundary condition (ABC), by which the transient plasma can be truncated, was validated. The frequency drift phenomenon for electromagnetic wave in a transient plasma slab and some other useful conclusions are obtained.

The simulated PM-spectrum fractal sea surfaces and the 3-D near-field distributed model of horn antenna are built, the near-field formulas of KA method are deduced. The near-field scattering coefficient and the Doppler echo signal of rough sea surfaces are calculated, the agreement with measured data proved the correctness and validity of the near-field scattering model.
