Sažetak
It is directly and universally applicable on any contemporary hydroacoustic antenna. Analytical expressions in general form are particularly appropriate for graphical presentation of functional dependence of directivity index on given parameters. Presented graphs of functional behavior in a two-dimensional system and especially in a three-dimensional coordinate system are an excellent base for standardization and quality evaluation of an antenna. With this model and with given mathematical expressions mathematical standards for applying hydroacoustic measurements of directivity pattern in the equations of hydrolocation are founded.
