Time-domain Double Diffraction for UWB Signals
In this paper, a heuristic time-domain uniform theory of diffraction (TD-UTD) coefficient for a double wedge obstruction is proposed. The coefficient is obtained by taking the inverse Laplace transform of the corresponding frequency domain (FD) solution that incorpo-rates higher-order diffracted field. The early-time approximations are employed to heuristically establish the double TD-UTD coefficients for the analysis of the diffraction by dispersive obstacle wedge. The proposed closed form time domain solution is in good agreement with the numerical inverse fast Fourier transform (IFFT) of the FD solution.
