Abstract
A measurement device includes a signal sensor unit having one or more signal sensors configured to measure a measurement signal in which a target signal and noise are mixed, a reference sensor unit having two or more reference sensors configured to measure a reference signal including the noise, and a processing unit. The processing unit includes a reference sensor data group unit configured to classify reference sensor data that is data of two or more reference signals measured by the two or more reference sensors of the reference sensor unit into two groups, a first-order signal processing unit configured to perform a noise cancelation process for signal sensor data using reference sensor data of a first group, and a second-order signal processing unit configured to perform a noise cancelation process for first-order signal-processed data using reference sensor data of a second group.
