Abstract
A method and apparatus are provided for estimating an inter-node distance between a sender node and a receiver node belonging to a network comprising a plurality of nodes arranged along towed acoustic linear antennas. An acoustic signal is transmitted from the sender node to the receiver node through an underwater acoustic channel. The method includes estimating the inter-node distance as a function of an estimate of a sound speed profile of the underwater acoustic channel, the sound speed profile depending on depth.

A method comprising:
- estimating an inter-node distance between a sender node and a receiver node belonging to a network comprising a plurality of nodes arranged along towed acoustic linear antennas, an acoustic signal being transmitted from the sender node to the receiver node through an underwater acoustic channel, wherein estimating comprises:
- estimating the inter-node distance as a function of an estimate of a sound speed profile of the underwater acoustic channel, said sound speed profile depending on depth.

A non-transitory computer-readable carrier medium storing a program which, when executed by a computer or a processor, causes the computer or the processor to carry out a method of estimating an inter-node distance between a sender node and a receiver node belonging to a network comprising a plurality of nodes arranged along towed acoustic linear antennas, an acoustic signal being transmitted from the sender node to the receiver node through an underwater acoustic channel, the method comprising estimating with the computer or processor the inter-node distance as a function of an estimate of a sound speed profile of the underwater acoustic channel, said sound speed profile depending on depth.
A device for estimating an inter-node distance between a sender node and a receiver node belonging to a network comprising a plurality of nodes arranged along towed acoustic linear antennas, an acoustic signal being transmitted from the sender node to the receiver node through an underwater acoustic channel, wherein the device comprises:
- means for obtaining an estimate of a sound speed profile of the underwater acoustic channel, said sound speed profile depending on depth;
- and
- means for estimating the inter-node distance as a function of said estimate of the sound speed profile.
