BUOY-BASED MARINE ELECTROMAGNETIC SIGNAL ACQUISITION SYSTEM

摘要

A sensor cable system for measuring electromagnetic response of the Earth'ssubsurface includes a sensor cabledeployable on the bottom of a body of water. The sensor cable has a pluralityof electromagnetic sensing devices thereon at spacedapart locations. A system control unit is in signal communication with thesensing elements. The system control unit includes atransceiver for communicating signals to and from a corresponding sensor cablesystem. The system control unit includes a globalpositioning system signal receiver. The system control unit includes aprocessor configurable to receive signals detected by sensingelements in the corresponding sensor cable system. The processor isconfigurable to compute stacked signals from the sensingelements in the sensor cable and from sensing elements in the correspondingsystem. The processor is configurable to calculate astatistical measure of the stacked signals. The system control unit isdisposed in a flotation device.
