Hilbert transform application to the impulse signal processing

Effective algorithm for processing impulse signals which are scattered by plane-layered media is discussed. The case, when effective thickness of layers is less than spatial size of an impulse is under consideration. Such problem of evaluating layers properties (thickness) is rather complicated for the implementation. Brief theoretical analysis of possibilities of various approaches for processing of signals is carried out. Computational algorithm and the corresponding software for evaluation not only a time delay, but also geometrical characteristics of the investigated structures are described. Both results of numerical modelling, experimental researches and sensitivity and resolution of different approaches are presented and discussed.
