The problem of determination of numerical characteristics of the non-uniform dielectric materials located in the closed waveguide measuring systems is considered in the paper. For a solution the method based on use of mathematical apparatus of artificial neural networks is offered. Overall performance of the neural network trained on not uniformity of spherical shape at determination of volume of asheric samples is investigated. The numerical results confirming operability of the offered method in practice are given.
