Synthesis of antennas located in a sea bay

Abstract

The synthesis and analysis of arrays in marine bays and closed basins were shown to be different from analogous questions in the deep sea. To form the beam pattern of an antenna working in continuous mode (impulses of long duration) one needs to take into consideration all factors, such as array shape, amplitude-phase distribution of particle velocity onto the array, bay geometry, acoustic features of water and sea bottom. We offer mathematical models of synthesis and analysis of the array placed in a marine bay. These models take into account factors of frontiers and bay bottom. The mathematical models are based on a strict solution of the Helmholtz equation by applying Green's function. The question of analysis and synthesis of the array is formulated as the exact task of mathematical physics. Results of digital exploration are reported.
