Properties of flat, vertically-aligned antenna array in presence of absolutely hard sphere, lying at the border of distribution of media “water – air”
Main Article Content
Abstract
While creating the perspective facilities for hydroacoustic weapons there is the urgent question about influence of ship girder, its bottom, ribs, fins and other structural units in ship girder on their electroacoustic parameters. The article describes the research on quantitative evaluations of sound field in flat, verticallyaligned antenna array in presence of surface ship girder, modeled with absolutely hard sphere that lies at the border of distribution of media “water – air”. The analytical correlations, being received, are used for numerical evaluation of sound fields in model systems “hydroacoustic station – surface ship”, “hydroacoustic station – free medium” and for comparison of received results between themselves. Bibl. 3, fig. 5.
