METHODS AND SYSTEMS FOR IMPROVED MEASUREMENT, ENTITY AND PARAMETER ESTIMATION, AND PATH PROPAGATION EFFECT MEASUREMENT AND MITIGATION IN SOURCE SIGNAL SEPARATION

摘要

A method of processing a signal includes taking a signal recorded by a plurality of signal recorders, applying at least one super-resolution technique to the signal to produce an oscillator peak representation of the signal comprising a plurality of frequency components for a plurality of oscillator peaks, computing at least one Cross Channel Complex Spectral Phase Evolution (XCSPE) attribute for the signal to produce a measure of a spatial evolution of the plurality of oscillator peaks between the signal, identifying a known predicted XCSPE curve (PXC) trace corresponding to the frequency components and at least one XCSPE attribute of the plurality of oscillator peaks and utilizing the identified PXC trace to determine a spatial attribute corresponding to an origin of the signal.
