Abstract : A technical approach using triple-phase comparison arrays with computer-bearing computations was begun with measurements reported here; these data are analyzed for adequacy and a site-evaluation criterion is presented. Need for redundant phase measurements was found. A pattern recognition approach is postulated as the means of implementing the needed data redundancy and is to be investigated in continuing work.
