INTERFERENCE TOMOGRAPHY OF THE SYNOPTIC INHOMOGENEITIES AND OCEAN-BOTTOM

The interference algorithm of the acoustic tomography of the ocean is discussed. In this method the synoptic inhomogeneities of the sound ve locity field are restored by the perturbations in the intermode phase differences. The intermode phase difference, in its turn, is determine d by the measured space distribution of the intensity (the interferenc e structure) of the acoustic field. The interference method is also ap plied for determining the vertical profiles of sound speed, density an d attenuation coefficient in the bottom. The possibility of using this method is numerically analysed for natural ocean conditions.
