Endfire seismic receiver and method of use
This patent describes an endfire seismic array. It comprises a marine cable with a plurality of hydrophones spaced along the length of the cable, means for orienting the cable in a substantially axial direction toward a seismic target irradiated by seismic radiation from a seismic source. The plurality of hydrophones receiving respective seismic reflections caused by target irradiation at time intervals dependent of their respective axial distances from the target. The hydrophones converting the respective received acoustic energy to corresponding respective electrical signals, and means for respectively phasing the respective electrical signals so that the phased electrical signals are additive, thereby producing pencil beams for frequencies across the seismic band.
