DETECTING SEISMIC EVENTS USING MULTISPAN SIGNALS

Systems and methods for detecting a mechanical disturbance are disclosed. One of the method may comprise the operation steps including: transmitting, by a transmitter (110), a pulse at a preset frequency along a first cable (150); receiving, by a receiver (120), a plurality of signals, wherein each...

Zusammenfassung:Systems and methods for detecting a mechanical disturbance are disclosed. One of the method may comprise the operation steps including: transmitting, by a transmitter (110), a pulse at a preset frequency along a first cable (150); receiving, by a receiver (120), a plurality of signals, wherein each of the plurality of signals travels along the first cable and a second cable (160) connected to the receiver for a corresponding span; calculating one or more differential phases, wherein each differential phase is calculated based on respective phases and the corresponding spans of two of the plurality of signals; and determining a localization of the mechanical disturbance based on the one or more differential phases.
