US 2025/0093545 A1 · SYSTEMS AND METHODS FOR RADIO FREQUENCY SENSING OF SEISMIC EVENTS

Abstract

Systems and methods for detecting or predicting a seismic event. The methods comprise, by a system: receiving at least one communication signal using a carrier recovery component with a fixed location remote from a source of the at least one communication signal; determining at least one of (i) phase deviations of the at least one communication signal over time and (ii) differential propagation delays over two paths which the at least one communication signal traveled; performing operations to detect patterns in at least one of the phase deviations and differential propagation delays that indicate an occurrence of seismic activity with level(s) of confidence; and using the level(s) of confidence to detect or predict the seismic event.

Dependent claims

A method for detecting or predicting an event using a direct passive phase change measurement approach, comprising:

receiving a communication signal at a system having a carrier recovery component with a fixed location remote from a location of a source of the communication signal;
using, by the system, the communication signal to generate a reference signal with a range of frequencies less than the range of frequencies of the communication signal;
determining, by the system, phase deviations in the communication signal over time by comparing the communication signal to the reference signal;
performing, by the system, operations to detect a pattern in the phase deviations that indicates occurrence of structural physical motion of the source with a level of confidence;
and
use, by the system, the level of confidence to detect or predict the event.
