Expendable volume reverberation profiler

摘要

An expendable volume reverberation profiler comprising an acoustic transmitter-receiver unit and the associated telemetry section which is hard wired to a point at the surface of the ocean. The transmitter-receiver unit is allowed to fall freely through the ocean and an acoustic signal is transmitted through the water while the receiver section is blanked out. The acoustic information received later by the receiver section is telemetered to the surface to develop a volume reverberation profile.
