Mode sign estimation to improve source depth estimation

This paper describes source depth estimation in shallow water environments using a Horizontal Line Array of hydrophones on the sea bottom. A method based on modal propagation, using mode amplitude modulus, has been proposed by Nicolas [1]. 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.
