1. A signal processing method comprising:
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,
wherein the source signal includes a plurality of signal components that are cyclic, and the plurality of signal components have different cycles from each other,
a time length of the template signal is longer than a cycle of a first signal component of the plurality of signal components and shorter than a time length of the processing target signal, and
a difference between the time length of the processing target signal and the time length of the template signal is longer than the cycle of the first signal component.
