description: The topic of the final qualification work: "Research of frequency characteristics of scattering of hydroacoustic signals".This work is devoted to the study of the frequency characteristics of a scattered hydroacoustic signal.Tasks that were solved in the course of the study:1) Review of the subject area, including consideration of issues related to hydroacoustic processes and frequency characteristics of scattered signals. 2) Construction of the initial mathematical model.3) Development of software for calculating the spectrum of a scattered hydroacoustic signal.4) Software testing using source data.5) Analysis of the received spectrum of the scattered signal.The work was carried out using the Matlab software package.As a result, the spectrum of the scattered signal was studied using specially developed software using interpolation algorithms and numerical methods.
