Abstract:
1. A method of processing a signal received by a phased array antenna, said method comprising: (i) receiving the signal via a plurality of antenna elements of said phased array antenna, said antenna elements being situated at a set of n loci; (ii) measuring the phase of the signal at each locus to produce a set of n sequential phase values; (iii) calculating the differences between neighboring phase values in the sequence according to: where Φmeasured k is the kth phase value in the sequence; (iv) calculating the differences between neighboring values of DIFF1 (v) rounding the values of DIFF2 (vi) summing neighboring values in the set of rounded values DIFF (vii) summing neighboring values of dΦ and (viii) adding the values Φ
