Abstract : A realtime system for the measurement of the bottom reflection coefficient using the AN/UQN-4 depth sounder was developed. Data provided by the system is transferred to the MTEDS database system where it is made available to the Acoustic Sediment Classification System (ASCS). In addition to the bottom reflection coefficient, the system also provides time and ship's position from a built-in GPS receiver, and depth data for the MTEDS database. Three sea tests provided data for system development. In addition, geophysical measurements, which were made during the sea tests by the Coastal Benthic Boundary Layer Special Research Project, were used to verify the system results. Basic design features of the system, both hardware and software, are discussed.
