“…The directional properties of a simple receiver antenna will be illustrated in the following analysis. This response function is complex valued, so that the results of the array response are usually expressed in terms of amplitude and phase spectra (Officer, 1958). The array amplitude spectral response can be written (for temporal frequency f = w/2n): [1!.3 .…”

“…Sound velocity should be determined with a precision instrument, for example, a Conductivity-Temperature-Depth (CTD) probe (see Gregg and Cox, 1971 (Officer, 1958) to find the time of travel, TT, of an acoustic pulse between the two points is the travel time TT multiplied by the arithmetic mean sound velocity c:…”

Analysis of a high resolution deep ocean acoustic navigation system

ABSTPACTA high resolution acoustic navigation system for ocean use is being developed at the Woods Hole Oceanographic Institution. The system can yield navigation fixes with respect to a bottom moored reference net with accuracies (on a fix to fix basis) of a few centimeters.In order to use the system to best advantage a survey is required to determine precisely the relative positions of the net elements.Each element combines a pulse transponder with a continuous wave (CW) beacon. Accumulated phase (Doppler shift of the CW beacon) between survey points is measured as well as acoustic travel times between survey points and transponders. Non-linear regression techniques are employed to develop a maximum likelihood estimator for net element positions based on these phase and travel time measurements. An approximate error covariance matrix is generated and an optimum choice of survey points is indicated. The combined system, using these selected locations for performing the survey, can yield reference mooring coordinates with error of ±1 meter. Improved precision appears to be limited by inaccuracies in the pulse and Doppler measuring system.
