Parametric separation applied to underwater acoustic multipath propagation

The authors focus on wave parameter estimation. They present a new method using a sliding spatial window along the antenna to improve the performance of parameter estimation and to estimate the shape of the wavefronts. First, ther recall the method which uses a maximum likelihood estimator (MLE) applied on broadband signals. The second part is devoted to applications on real data where the signal to be studied is obtained from a single moving hydrophone measuring the spatial properties of the acoustic multipath propagation
