Abstract: A possibility to determine the acoustic properties of marine sediments using parametric profiler. Instead of omnidirectional sources are encouraged to use the parametric scanning antenna system. Scanning characteristics of the antenna is discrete steps. To account arising from this delay in the algorithm for determining the speed of sound introduced an additional kinematic correction. To test the proposed amendments is simulated.

Keywords: nonlinear underwater acoustics, chirp, the speed of sound.
