Sažetak
In this paper will be presented a new universal procedure of calculating of directivity index dependent of the measured directivity pattern of a SONAR antenna. The procedure derives from an idealized model of directivity pattern. It is directly and universally applicable on any contemporary sonar 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.
