SEISMIC RADAR

SCIENCE HORIZONS HAS DEVELOPED A PROPRIETARY METHOD OF DISPLAYING SEISMIC DATA, CALLED SEISMIC RADAR, WHICH USES THE HIGH RESOLUTION, COLOR GRAPHICS CAPABILITIES OF THE DARPA SCIENTIFIC WORKSTATION TO PROVIDE A "RADAR LIKE" DISPLAY OF THE SEISMIC DATA GENERATED BY AN ARRAY OF SEISMOMETERS. THE PARAMETERS ABLE TO BE EXTRACTED BY AN ANALYST FROM THE SEISMIC. RADAR DISPLAY ARE THE VELOCITY, AZIMUTH, AND AMPLITUDE OF THE PHASE. SEISMIC RADAR WAS DEVELOPED BY SCIENCE HORIZONS TO FULFILL THE DEMONSTRATION REQUIREMENTS ASSOCIATED WITH THE DARPA SCIENTIFIC WORKSTATION. HOWEVER, IT SOON BECAME APPARENT THAT THE INFORMATION CONTYAINED IN THE SEISMIC RADAR DISPLAY, WHILE AN EFFECTIVE DEMONSTRATION VEHICLE FOR THE WORKSTATION, SHOULD ALSO BE EXTREMELY USEFUL TO AN ANALYST WHO REQUIRES NEAR-REAL-TIME, COMPREHENSIBLE ESTIMATES OF THE AZIMUTH, VELOCITY, AND AMPLITUDE OF THE INDIVIDUAL PHASES WHICH COMPRISE A SEISMIC EVENT. THEREFORE, THE PROBLEM TO BE ADDRESSED DURING PHASE I IS TO DEMONSTRATE THE FEASIBILITY OF USING THE PROCESSING AND DISPLAY FEATURES EMBODIED IN SEISMIC RADAR IN ORDER TO ASSIST AN ANALYST IN DETECTING AND LOCATING SEISMIC EVENTS.
