ABSTRACT:
A method for processing signals, such as a tomography signal, in the time domain provides both high spatial resolution and high frequency resolution but at low cost. The method uses non-linear regression with a sinusoidal model to fit a sine wave to a portion of the signal that is less than a full cycle of a wave of the signal.
