Preliminary Report on the Cooley-BIFI Experiment.
Abstract
An underwater acoustic propagation experiment was jointly conducted by NUSC at New London, Connecticut and a team from Cooley Electronics Laboratory at The University of Michigan. A special pseudo-random waveform, complement phase modulating a carrier was transmitted continuously for 58.5 hours. The power and angle of the carrier, the power in the sidebands, and the noise power in the signal bandwidth were recorded continuously during this time. In addition, the total power and the power spectrum in a narrow band about the carrier were recorded as a measure of the forward scattering reverberation. Also, the cross-correlation of the received signal with a stored reference was continuously computed in order to examine the multipath structure and its stability. The report presents a brief description of the experiment and the on-line analysis of the results. (Author)
