Abstract

The statistical approach to the problem of the acoustic sources image re- construction has been suggested. With the help of this approach the recon- struction algorithms are synthesized for uncorrelated and coherent sources. 1 Introduction As it is well-known, the problem of sound sources image reconstruction is related to the type of inverse acoustical problems. Traditionaly this problem is formulated in the following way. In some space domain ft the volume or surface sound sources g(w, r) are located. These sources produce the field S(u, r) at the elements of the receiving antenna array S(w,r,) = f Gg(u>,Ti,r) q(u>,r) dr (1) Jn where G(u>, r, r') for volume sources G,(w,r,r') = {
