TRIBAND: THE THREE BAND FILTER FOR THE CONTINUING MIMI EXPERIMENT.

Abstract

An experiment was conducted as part of the continuing study of sound propagation in the Straits of Florida. A 420-Hz continuous wave (CW) signal was transmitted, received at the 7-mile hydrophone, and processed by the Linc-8 on-line digital processor. The processing yielded the magnitude and phase of the reception in a 1/16-Hz band, the magnitude of the reception in a 1-Hz band but excluding the 1/16-Hz band, and the magnitude of the reception in a 16-Hz band that excluded the 1-Hz band. All bands were centered at 420 Hz. The purposes of the experiment were to verify the possibility of such a three-band analysis and to obtain typical relative power ratios to aid in the design of analog triband phase coherent demodulation.
