Wave energy source location by amplitude and phase measurement
Abstract
Abstract REAL OR VIRTUAL SOURCES OF SINGLE FREQUENCY RADIATION ARE LOCATED BY CHARTING THE AMPLITUDE AND RELATIVE PHASE OF THE RADIATIONS PASSING THROUGH A PLANE SURFACE, AND BY THEN ANALYZING THE RESULTANT CHART. IN SEISMIC EXPLORATION, VIRTUAL SOUND SOURCES ARE CREATED BELOW INTERFACES BY A SINGLE FREQUENCY MECHANICAL VIBRATOR, AND THE REFLECTED SOUND WAVES ARE CHARTED. NOISE PROBLEMS ARE OVERCOME WITH HIGH Q FILTERING AND CORRELATION PROCESSING TECHNIQUES. THE USE OF SINGLE FREQUENCY EXCITATION SOURCE MAKES IT POSSIBLE TO CHART THE SOUND RADIATIONS AT A LEISURELY RATE WITH A SINGLE SOUND DETECTION UNIT, AND ALLOWS DETERMINATION OF THE SLANT OF SUBTERRANEAN INTERFACES AS WELL AS THE DEPTH OF THE INTERFACES.
