APPLYING RESAMPLING TECHNIQUES TO LARGE DATA SETS

Not Available A remotely monitored fiber optic sensor system which exceeds the Navy's performance requirements in a compact package will be demonstrated during Phase I. The orientation of the axis of the sensor head relative to the horizontal component of the earth's magnetic field is precisely determined using a novel optical readout scheme in conjunction with a conventional magnetic compass. In addition to magnetic heading, the system also measures the pitch of the sensor head. Compasses of this type, each connected to the dry-end signal conditioning unit by a single optical fiber, are suitable for mounting in a towed array cable to determine its trajectory in the ocean. The wet end of the system requires no electrical power. The cost of instrumenting an array cable is minimized because the sensor head is simple in design and contains only inexpensive components, and because many sensors can be multiplexed using a single light source.
