摘要
A method for estimating an underwater acoustic sound velocity in a network of acoustic nodes arranged along towed acoustic linear antennas and in which a plurality of acoustic signals are transmitted between the nodes, the method comprising steps of: obtaining two predetermined distances each separating a couple of nodes ((A,B), (B,C)) placed along a same first acoustic linear antenna (31); for each couple of first and second nodes ((A,B), (B,C)), obtaining a first propagation duration of an acoustic signal transmitted between said first node and a third node (D) placed along a second acoustic linear antenna (32) and a second propagation duration of an acoustic signal transmitted between said second node and said third node (D); and estimating said underwater acoustic sound velocity, as a function of said two predetermined distances and said first and second propagation durations obtained for each couple of nodes.
