Abstract
An submarine target device comprising an acoustic receiver, an acoustic transmitter and processing means adapted to perform a first cycle of operations comprising detecting within an acoustic stream captured by the acoustic receiver, the start of a first signal corresponding to characteristics of at least one acoustic transmitter remote from at least one detector; triggering the recording of the first signal; detecting, within the acoustic stream, the end of the first signal and triggering the cessation of recording; then a second cycle of operations comprising detecting, within the acoustic stream, the start of a second signal corresponding to said characteristics; and triggering the transmission of the first signal, via the acoustic transmitter.

A submarine target device comprising an acoustic receiver, an acoustic transmitter and processing means adapted to perform a first cycle of operations comprising:
- detection within an acoustic stream captured by said acoustic receiver, of the start of a first acoustic signal corresponding to characteristics of at least one remote acoustic transmitter of at least one detector;
- following detection of the start of said first signal, triggering recording of said first signal;
- detection within said acoustic stream of the end of said first signal;
- following detection of the end of said first signal, stopping recording of said first signal;
- followed by a second cycle of operations comprising:
- detection within said acoustic stream, of the start of a second acoustic signal of the same nature as the first signal and corresponding to said characteristics;
- and following detection of the start of said second signal, triggering transmission via said acoustic transmitter of the first signal recorded during the first cycle of operations.
A method for an submarine target comprising an acoustic receiver and an acoustic transmitter, said method comprising a first cycle of operations comprising:
- detection, within an acoustic stream captured by said acoustic receiver, of the start of a first acoustic signal corresponding to characteristics of at least one acoustic transmitter remote from at least one detector;
- following detection of the start of said first signal, triggering recording of said first signal;
- detection of the end of said first signal within said acoustic stream;
- following detection of the end of said first signal, stopping recording of said first signal;
- followed by a second cycle of operations comprising:
- detection, within said acoustic stream, of the start of a second acoustic signal of the same nature as the first signal and corresponding to said characteristics;
- and following detection of the start of said second signal, triggering transmission, via said acoustic transmitter, of the first signal recorded during the first cycle of operations.
