Phase Fluctuation Enhanced Adaptive Processor

Abstract

The invention uses phase fluctuations in each frequency bin to modify the exponents of pressure amplitudes (or power magnitudes) for each successive realization of a signal. As the magnitudes of the phase fluctuations decrease (i.e., signal has small magnitudes and the noise has large ones), the exponents increase. The modified pressures are summed and averaged. The resulting average is then raised to an exponent that is the average of the exponents of the individual pressures (or power magnitudes). All individual exponents and the averaged exponent in each bin are preferably bounded between optimal values of 2 and -4. The exponents will be negative for noise (attenuation), and in between for clutter signals.
