Zusammenfassung:	In the summer of 1970, a field test was conducted to determine if a portabld signal processing unit built around a small digital computer could be used to run specific underwater propagation experiments in the Straits of Florida. A periodic broadband signal modulating a 420 Hz carrier was transmitted continuously across the Straits of Florida for 9 days. At the receiving site, the power an 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. (Author)
