UNDERWATER SOUND PROPAGATION IN THE STRAITS OF FLORIDA: THE MIMI CONTINUOUS AND SAMPLED RECEPTIONS OF 11, 12, AND 13 AUGUST 1966.

Abstract

As a part of a study of underwater sound propagation in the Straits of Florida, called Project MIMI, 24-hour continuous and sampled receptions were taken on 11, 12, and 13 August 1966. The amplitude modulation of the 420-Hz carrier wave by a maximal pseudo-random sequence (AMSEQ) simultaneously yields information about the oceanic modulation of the carrier (continuous wave analysis), and the multipath sound propagation (sequence analysis). This report describes the experiment and the data processing and presents the results in photographic form as amplitude and phase versus time displays. (Author)
