摘要:
A new approach to resolve overlapping echoes is proposed. Inverse filtering is performed in a windowed frequency interval to avoid the enhancement of highly distorted signal spectrum. Using the partially inverse filtered signal spectrum as the data base, nonlinear spectral estimation techniques are then applied to resolve the number of overlapping echoes present and to obtain high resolution estimate of the individual echo time delays. Numerical and experimental results verify the effectiveness of the proposed new approach.
