Abstract :
Application of neural network ideology for layered dielectric structure nondestructive testing is under consideration. The 3-layered feed-forward with activation function as a sigmoid (S-shaped) was chosen. Time-domain signals synthesized from ultrawideband data is used as input signal. Levenberg-Marquardt algorithm was used for training of the network. Some results of numerical simulation for two-layered structure with air insertion in presence of Gaussian additive noise are demonstrated
