Measurement of acoustic reflection coefficients using the power cepstrum

A technique for measuring acoustic reflection coefficients using the power cepstrum is presented and discussed. The power cepstrum is used to obtain the impulse response of the reflector which is Fourier transformed to yield the reflection coefficient. Constraints on the acoustic source, aliasing, and noise effects are examined and procedures for reducing these effects are presented. An example computation of a reflection coefficient is included.
