SPIRAL SENSOR CONFIGURATION FOR SEISMIC BEAMFORMING AND FOCUSING

摘要

A seismic sensor array includes a plurality of seismic sensors disposed on a line. The line is arranged in a spiral. The seismic sensors are disposed at at least one of equal angular spacing between adjacent sensors and equal linear spacing between adjacent sensors. A recording system is in signal communication with each of the seismic sensors. The recording system includes means for beam steering a response of the sensors.
