Sažetak
This paper presents a universal procedure of precise de-embedding of directivity index and effective aperture dependent of the suppressed side lobes on measured cone directivity pattern of sonar antenna. The procedure is derived on an idealized model of cone directivity pattern characteristic of antenna. It is directly and universally applicable on any contemporary sonar or hydroacoustic communication system with cone directivity pattern. In accordance with given expressions of directivity index and effective aperture of hydroacoustical ring antenna, this paper gives graphical presentation of the impact of total transmission losses in dependence on directivity index and suppress of side lobes level on the sonar range. Presented graphs of functional behavior in a two-dimensional system and especially in a three-dimensional coordinate system are an excellent base for standardization, unification and quality evaluation of sonar or radar systems and also medical scanners.
