| Resumo: | Title screen The paper proposes phase-frequency algorithms with equilibrium and non-equilibrium processing based on the pre-developed phase-frequency tracking methods for resolving complex signals in wave seismic field images. It further shows that transition to equilibrium processing enables significant reduction of requirements to apriori information on the properties of useful signals, while non-equilibrium processing increases the resolution of the signals to a great extent. The conducted analytical argument and simulations testified that the algorithms can assure a sufficiently high extraction of signals in their interference zones and harder incoherent noise at propagation of complex signals in dispersive media. The simulation results are justified by real data obtained in processing of seismic wave fields. |
