pulse is transmitted by the transceiver and detected by the subsea transponder, which replies with its own acoustic pulse. This return pulse is detected by the shipboard transceiver. The time from the transmission of the initial acoustic pulse until the reply is detected is measured by the USBL

In this case, the "topside" processing happens inside the vehicle to allow it to locate the transponder for applications such as automatic docking, 214: 82:. The transceiver head normally contains three or more transducers separated by a baseline of 10 cm or less, hence the "short baseline" name.
