The Benthos Directional Acoustic Transponder (DAT) is anextension to the Teledyne Benthos ATM-900 Series modem, which automatically estimates the azimuthal and vertical arrival angles of a message sent by a remote modem. The system is a modified ultra-short baseline (USBL) which uses a broadband component of a typical modem message to form estimates of arrival angle(s). While conventional USBL devices employ tonal signals, our appropriate processing of wideband signals provides far better-combined range and arrival angle estimation, especially at a low Signal to Noise Ratio (SNR). Our device offers a clear 360-degree field of view in azimuth, and an approximate vertical coverage spanning + 90º overhead to -50º below horizontal.
