The problem of reconstruction of the sound speed profile in the water column in a shallowsea waveguide by means of geoacoustic inversion from single-hydrophone recording of a pulse signal is considered. A method for solving this problem with the use of high-performance computer systems is developed and implemented. Numerical experiments performed by using this algorithm show that the sound speed profile in the water column can be reconstructed on the basis of some very rough estimates for geoacoustic parameters of the bottom. The use of these rough estimates does not affect the accuracy of sound speed profile reconstruction provided that the signal spectrum contains some components of sufficiently high frequency.
