Résumé

This paper describes source depth estimation in shallow water environments using a Horizontal Line Array of hydro\-phones on the sea bottom. A method based on modal propagation, using mode amplitude modulus, has been proposed by Nicolas \cite{Nicolas06}. As knowledge of the sign of mode amplitudes can improve source depth estimation, we present a estimator of these signs and integrate them in the source depth estimation method. Results on real data are shown.
