文摘

On the basis of diffraction problem known solutions on a wedge in the case of harmonic effects using frequency method was analyzed the UWB pulse scattering on the impedance wedge. The features of the diffraction different kinds of pulses were revealed. We were defined the influence of the wedge’s electrical and geometrical parameters, sensing conditions and monitoring, as well as probing signal spectrum shape and the diffraction pulse energy. In study of the time dependence influence the type of probe pulse on the scattering field was tested a time-frequency method.
