Abstract
Experimental data on the angular structure of the sound field on the shelf of the Sea of Japan are discussed. The data are obtained by using the vector-phase processing of complex signals in the form of M-sequences with a central frequency of 2500 Hz. With the parameters of the water bulk being monitored, an unambiguous relation is established between the variability of the temperature regime on a fixed acoustic path and the arrival times and angles. It is shown that the use of vector receivers in ocean tomography provides an additional independent parameter of the pulse response of the underwater waveguide and leads to an increase in the efficiency of solving the problem of reconstructing the hydrophysical fields from the data of acoustic sensing.
