Abstract

The definition of tactical and technical requirements for new hydroacoustic stations for surface ships or upgrades to existing ones requires the determination of the correlation between the basic performance characteristics of hydroacoustic stations and the parameters of hydroacoustic antennas and transducers that are part of their composition is considered. The characteristics of hydroacoustic stations efficiency are taken as their energy range and separation capacities. It is shown that such characteristics of hydroacoustic stations efficiency as range, angular characteristics and speed of targets are determined by a number of parameters of hydroacoustic antennas and transducers of these stations. As parameters of hydroacoustic antennas and transducers the frequencies of mechanical resonances of the transducers, their efficiency coefficients, specific radiation power, directional characteristics and concentration coefficients of hydroacoustic antennas are determined. The hydroacoustic signals are found to have the frequency spectrum that is in the spectrum of mechanical resonance of the hydroacoustic transducers, as only in this case the electroacoustic coefficient of performance of the transducers has the maximum value. It is shown that the frequency of mechanical resonance of sounder aerial transducers is of significant importance for the value of energy range of sounder, because it affects not only the maximum value of the radiated power capacity, but also the minimum value of space attenuation coefficient of hydroacoustic signals. The analytical relationship between the characteristics of the efficiency of hydroacoustic stations and the parameters of their hydroacoustic antennas and transducers is presented. The physical peculiarities of their dependencies are determined.
