Abstract: The received phase of a transmitted acoustic continuous wave (cw) signal has been shown to provide a measure of ocean parameters along the propagation path. This paper contains a review of the problems encountered in measuring phase and considerations for designing a phase estimation algorithm. The algorithm must consider the characteristics of the phase process, the noise, and especially the problem of multipath fades. Spectral analysis of the phase process must be done with care because of the large fraction of energy concentrated at the low (semidiurnal and below) frequencies. An analysis of quantization error in the measurement of phase and estimation of the phase spectrum is presented. [Work supported by ONR, Code 222.]
