Abstract:

This work describes a set of digital signal processing techniques and associated hardware that were developed at the Cooley Electronics Laboratory CEL of The University of Michigan for use in measuring the multipath structure of acoustic propagation channels in the ocean. The design and construction of this hardware, its programming and its use to measure multipaths were done as part of CELs support of the 1981 Ocean Acoustic Tomography Demonstration Experiment. The purpose of the Tomography experiment was to use acoustic probe signals to determine the thermal structure of a volume of the ocean which, at the surface, corresponded to a square 300 km per side.
