Abstract
A signal processing method includes: a processing target signal generation step of generating a processing target signal that is a time-series signal, based on a source signal that is a time-series signal corresponding to a physical quantity generated in a steady state of a target object; and a correlated signal generation step of performing correlation filter processing between a template signal that is a time-series signal generated based on the source signal, and the processing target signal, and generating a correlated signal that is a time-series signal.
