Study on SAR Imaging of The Targets Coated with Plasma Sheath

In this paper, the far-field echo from plasma coated targets is calculated with SO-FDTD (Shift operator finite difference time domain) method when irradiated by a modulated Gauss impulse waveform. And based on the echo data, the synthetic aperture radar (SAR) imaging of the plasma coated targets were studied with various plasma characteristics and radar incident waveform. The effect of electron density and collision frequency on imaging quality have been summarized in this paper. And other parameters, such as radar angle width, view width and center frequency will be reported in the following papers.
