The determination process is repeated with one of the adjacent points Q as a new reference point P, and the effectiveness/ineffectiveness of the whole data are determined. After that, an extrapolated value of an adjacent point C adjacent to the one of the adjacent points Q is found by the fitting expression of a reference point A, which is one of the effective data, and the point C is unwrapped so that the phase difference from the extrapolated value is within ±π (S8). Then, the similar unwrapping process is repeated with a point adjacent to the reference point A as a new reference point A to unwrap the whole effective data.  <P>COPYRIGHT: (C)2003,JPO
