Paper Abstract

The theoretical concept and algorithms of experimental signal processing, permitting the determination of complex acoustical source characteristics from near-field data, are discussed. The algorithms are based on two different approaches: on the integral transformations using a high-frequency approximation and on the methods of parametric estimation theory. The theoretical part of near-field methods includes the design of algorithms of measured data transformation, the investigation of the angular sectors of trustworthy determination of the direction pattern and resolution of image reconstruction, and the analysis of requirements for the receiving system. The numerical simulation of the direction pattern reconstruction and experimental result of the reconstruction of the ship acoustical images in the frequency-spatial domain from linear to array data are included.
