Abstract.
A method
for calculating the distance to the object in a medium with
the
presence
of frequency dispersion of a phase velocity is considered. An analytical expression
is obtained for the probe function characteristic of the dispersion law of collisionless plasma, waveguide
structures of electromagnetic and elastic waves. A method for accelerating the
proposed method by reducing the computational complexity from
O(N2) to
O(NlogN) operations
using the fast Fourier transform algorithm is proposed.
Key words:
dispersion, FFT, broadband signals.
