FAR-FIELD DETECTION DEVICE, SYSTEM AND METHOD

摘要

A far-field detection apparatus for measuring a far-field signature of a seismic source includes a main tow cable, a depth control device, sensor lines, at least two deflectors and seismic sensors. The depth control device is attached to the main tow cable. Each of the sensor lines has a first end attached to the main tow cable. Each of the deflectors is attached to a second end of the sensor lines, respectively. The deflectors are configured to generate forces pulling the sensor lines away from the main tow cable. The seismic sensors are attached between the first end and the second end of each of the sensor lines. The seismic sensors are configured to measure seismic waves generated by the seismic source.
