Abstract :
An analysis of results of FDTD-simulation of UWB electromagnetic pulse wave diffraction by a layered dispersive structure like soil is presented in this work. The radar images of this structure obtained at different spatial locations of the antenna system for various dielectric parameters of layers are constructed and analyzed in the paper. The amplitude-time characteristics of reflected pulses are analyzed too.
