Algorithms for Separating the Sum of Vibrations and Identifying their Sources

The situation is considered when signals from vibrating objects propagate in an elastic medium and are registered by several sensors remote from each other. The task is to interpret the registered signals in the form of the sum (superposition) of several components. It is assumed known (for physical reasons) belonging the structure of components to one of the types, namely – to harmonic oscilations with certain laws of change in frequency and amplitude. The algorithms of interpretation of the total signal are investigated, their speed and accuracy are estimated.
