Abstract:

From an active underwater acoustics experiment, we intend to estimate the time delays of the multipath propagation, in the case where the time differences of arrival are not large enough to be treated by classical methods. After estimating the propagation filter transfer function, we apply the autoregressive modelization to these frequential data. We deduce the delays values from the poles locations of the AR model. Simulations of the processing are presented. Finally, the method is applied to real data.
