METHODS OF SELECTION AND ANALYSIS OF CHARACTERISTICS OF NORMAL WAVES (MODES) IN THE SHALLOW SEA HYDROACOUSTIC WAVEGUIDE
This article discusses methods of extraction and analysis of the characteristics of normal waves (modes) in the hydroacoustic waveguide, using complex pulses with linear frequency modulation. The results of performance evaluation mod (number, amplitude, the relative propagation delay) from the experimental data obtained in a shallow sea are adduced
