Abstract
ALGORITHMS ARE DERIVED THAT DEFINE THE PATHS OF MAXIMUM COHERENCY FOR A SEISMIC EVENT GENERATED BY FIRING AN ARTILLERY WEAPON FROM AN ARBITRARY LOCATION. SIGNAL EXTRACTION TECHNIQUES ARE DESCRIBED TO EXTRACT THE COHERENT SIGNAL FROM AN EVENT RECORDED ON MULTIPLE RECEIVERS. SIMULATED BATTLEFIELD RECORDINGS ARE GENERATED BY TREATING THE SEISMIC SIGNATURE OF ARTILLERY WEAPONS AS IMPULSE RESPONSES FROM TIME-VARYING DIGITAL BAND PASS FILTERS. TECHNIQUES TO COMBINE MULTIPLE SHOTS FROM A VARIETY OF WEAPONS TYPES, PLUS ADDITION OF RANDOM NOISE ARE DESCRIBED. APPLICATION OF INVERSE FILTERS TO DISTINGUISH BETWEEN WEAPONS TYPE AS DISCUSSED. CALIBRATION TECHNIQUES TO ACCURATELY RELATE SEISMIC DERIVED BATTERY LOCATIONS TO TRUE GROUND COORDINATES ARE DESCRIBED. ANTICIPATED BENEFITS/POTENTIAL COMMERCIAL APPLICATIONS - MILITARY - LOCATE ENEMY BATTERIES BY ANALYZING ACOUSTIC AND SEISMIC WAVES GENERATED BY FIRING THE WEAPON. COMMERCIAL - NONE. KEY WORDS - ACOUSTICS, INVERSE FILTER, SEISMICS, BANDPASS FILTER, NETWORK, FILTER THEORY.
