Abstract: A method for estimating a position of a first acoustic linear antenna relative to a second acoustic linear antenna belonging to a network of towed acoustic linear antennas on which are arranged a plurality of nodes. The method includes: setting a first plurality of nodes arranged on the first antenna to act as sender nodes and a second plurality of nodes arranged on the second antenna to act as receiver nodes; forming a first group of sender nodes each sending a same first acoustic signature; for each receiver node: obtaining a propagation duration and establishing a geometrical figure representative of potential positions of a sender node, based on the propagation duration and the first acoustic signature; determining a set of common points between the geometrical figures; estimating the position of the first antenna relative to the second antenna based on the set of common points.
