IMPROVED MULTIFOLD CROSS-CORRELATION FOR BOREHOLE SIGNALS Abstract Methods and apparatuses are described for improving the cross-correlation of a plurality of signals derived in an investigation of a borehole. The technique involves the testing of signs of samples employed in forming a cross- product during a cross-correlation. Sign conditions representa- tive of a good match are so recognized and the resulting cross- product modified if needed for constructive contribution to the cross-corralation. Sign conditions indicative of a lack of correspondence between samples can also be detected so that cross-products from such samples can be prevented from adding to correlation peaks when an even number of negative samples are present. Several embodiments are described.
