Abstract:
1. A method comprising: (a) acquiring a plurality of signals, each having a phase component of observed phase value characterized by a parametric model expression, the parametric model expression defined by a set of parameters of unknown value; (b) establishing a set of values for the parameters; (c) determining a modeled phase value for each of the phase components by evaluating the parametric expression with the set of values; (d) determining a statistical cost for the set of parameter values as a function of a difference between the observed phase value and the modeled phase value of each of the phase components averaged over the plurality of signals; (e) repeating (b)-(d) until finding an average statistical cost that is less than a predetermined threshold; and (f) conveying those values for the parameters corresponding to the parametric expression that provides the desired value of average statistical cost.
