Abstract
The diagnostics of the noise acoustical sources from near-field data is considered. The algorithms allowing the determination of the equivalent elementary source distribution along a radiator and the far-field reconstruction from near-field measurements are presented. Some components of the total reconstruction error are analyzed.
