Underwater Sound Propagation in the Straits of Florida: The Preliminary Analysis of the MIMI Experiment of 1970.
Abstract
An underwater acoustic propagation experiment was conducted during the month of November 1970 as part of the Project MIMI propagation and signal processing research program. A periodic broadband signal, modulating a 420 HZ carrier was transmitted continuously across the Straits of Florida for 19 days. At the receiving site, the power and phase angle of the carrier, the power in the signal sidebands, and the noise power in the signal band were measured. In addition, the total power and the power spectrum in a narrow band about the carrier line were determined as a measure of the modulation due to the forward-scattered surface reverberation. Finally, the correlation of the received signal with a stored reference was computed to measure the multipath structure and its stability. This report presents a brief description of the acoustical range, the experiment, and the preliminary analysis of the data. (Author)
