DESCRIPTION:Present research is concerned with numerical modelling of Andr
 eev scattering technique used for detection of quantized vortices in $^3$H
 e-B. The results of numerical analysis of Andreev reflection by three-dime
 nsional turbulent structures are reported. We analyse the Andreev scatteri
 ng by a dense vortex tangle and calculate the spectral characteristics of 
 the retroreflected beam of thermal excitations. The obtained results are i
 n agreement with experimental observations.\n
