Abstract
A measurement system determining a correspondence between detection signals regarding distance and relative speed of multiple targets includes: a first result acquisition unit performing FFT processing on a signal generated based on both of an in-phase component and an orthogonal component of the reception light, and acquiring, as a first result, a peak frequency regarding the distance and a peak frequency regarding the relative speed; a second result acquisition unit acquiring, as a second result, a peak frequency detected by performing FFT processing on at least one of the in-phase component signal and the orthogonal component signal; and a combination determination unit determining, as a third result, a combination of correspondence between the distance and the relative speed based on both of the first result and the second result.
