Harmonic ambiguity resolver and inter array harmonic tracker

A method for resolving harmonic ambiguity from a frequency spectrum, comprising the steps of:

• selecting a component of a target signature fselected consisting of a single tone from a set of tones related to a target, as a candidate member of a harmonic family;
• calculating an N×M ambiguity matrix comprising a set of all possible harmonic families that fselected can be a member of based on two anchors, zero and fselected where N comprises all possible harmonic members (integers of from 1 to N) and M comprises all possible hypothetical fundamentals (fo=fselected/(1 thru N));
• calculating templates comprising one/zero matrices for each column of the N×M ambiguity matrix in order to weight the columns to reduce the risk of ambiguous solutions;
• and developing data filters based on the weighted matrix.
